path type error and not found changes (#13007)
# Description
Instead of an empty string, this PR changes `path type` to return null
if the path does not exist. If some other IO error is encountered, then
that error is bubbled up instead of treating it as a "not found" case.

# User-Facing Changes
- `path type` will now return null instead of an empty string, which is
technically a breaking change. In most cases though, I think this
shouldn't affect the behavior of scripts too much.
- `path type` can now error instead of returning an empty string if some
other IO error besides a "not found" error occurs.

Since this PR introduces breaking changes, it should be merged after the
0.94.1 patch.

After parsing menu code, the changes weren't merged into the engine
state, which didn't produce any errors (somehow?) until the recent span
ID refactors. With this PR, menus get a new cloned engine state with the
parsed changes correctly merged in.

Hopefully fixes https://github.com/nushell/nushell/issues/13118

Remove old sys command behavior (#13114)
# Description

Removes the old, deprecated behavior of the `sys` command. That is, it
will no longer return the full system information record.

# User-Facing Changes

Breaking change: `sys` no longer outputs anything and will instead
display help text.

Deprecate --numbered from for (#13112)
# Description

#7777 removed the `--numbered` flag from `each`, `par-each`, `reduce`,
and `each while`. It was suggested at the time that it should be removed
from `for` as well, but for several reasons it wasn't.

This PR deprecates `--numbered` in anticipation of removing it in 0.96.

Note: Please review carefully, as this is my first "real" Rust/Nushell
code. I was hoping that some prior commit would be useful as a template,
but since this was an argument on a parser keyword, I didn't find too
much useful. So I had to actually find the relevant helpers in the code
and `nu_protocol` doc and learn how to use them - oh darn ;-) But please
make sure I did it correctly.

# User-Facing Changes

* Use of `--numbered` will result in a deprecation warning.
* Changed help example to demonstrate the new syntax.
* Help shows deprecation notice on the flag

Part of https://github.com/nushell/nushell/issues/12963, step 2.

This PR refactors changes the use of `expression.span` to
`expression.span_id` via a new helper `Expression::span()`. A new
`GetSpan` is added to abstract getting the span from both `EngineState`
and `StateWorkingSet`.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->

`format pattern` loses the ability to use variables in the pattern,
e.g., `... | format pattern 'value of {$it.name} is {$it.value}'`. This
is because the command did a custom parse-eval cycle, creating spans
that are not merged into the main engine state. We could clone the
engine state, add Clone trait to StateDelta and merge the cloned delta
to the cloned state, but IMO there is not much value from having this
ability, since we have string interpolation nowadays: `... | $"value of
($in.name) is ($in.value)"`.

Fix the colors when completing using a relative path (#12898)
# Description
Fixes a bug where the autocompletion menu has the wrong colors due to
'std::fs::symlink_metadata' not being able to handle relative paths.
Attached below are screenshots before and after applying the commit, in
which the colors are wrong when autocompleting on a path prefixed by a
tilde, whereas the same directory is highlighted correctly when prefixed
by a dot.

Use native toml datetime type in to toml (#13018)
# Description

Makes `to toml` use the `toml::value::Datetime` type, so that `to toml`
serializes dates properly.


# User-Facing Changes

`to toml` will now encode dates differently, in a native format instead
of a string. This could, in theory, break some workflows:

```Nushell
# Before:

Allow stor insert and stor update to accept pipeline input (#12882)
- this PR should close #11433 

# Description
This PR implements pipeline input support for the stor insert and stor
update commands,
enabling users to directly pass data to these commands without relying
solely on flag parameters.

Previously, it was only possible to specify the record data using flag
parameters,
which could be less intuitive and become cumbersome:

```bash
stor insert --table-name nudb --data-record {bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17}
stor update --table-name nudb --update-record {str1: nushell datetime1: 2020-04-17}
```

Now it is also possible to pass a record through pipeline input:

```bash
{bool1: true, int1: 5, float1: 1.1, str1: fdncred, datetime1: 2023-04-17} | stor insert --table-name nudb
{str1: nushell datetime1: 2020-04-17} | stor update --table-name nudb"
```

Changes made on code:

- Modified stor insert and stor update to accept a record from the
pipeline.
- Added logic to handle data from the pipeline record.
- Implemented an error case to prevent simultaneous data input from both
pipeline and flag.

# User-facing changes

Returns an error when both ways of inserting data are used.

The examples for both commands were updated and in each command, when
the -d or -u fags are being used at the same time as input is being
passed through the pipeline, it returns an error:


![image](https://github.com/nushell/nushell/assets/120738170/c5b15c1b-716a-4df4-95e8-3bca8f7ae224)

Also returns an error when both of them are missing:

Overhaul explore config (#13075)
Configuration in `explore` has always been confusing to me. This PR
overhauls (and simplifies, I think) how configuration is done.

# Details

1. Configuration is now strongly typed. In `Explore::run()` we create an
`ExploreConfig` struct from the more general Nu configuration and
arguments to `explore`, then pass that struct to other parts of
`explore` that need configuration. IMO this is a lot easier to reason
about and trace than the previous approach of creating a
`HashMap<String, Value>` and then using that to make various structs
elsewhere.
2. We now inherit more configuration from the config used for regular Nu
tables
1. Border/line styling now uses the `separator` style used for regular
Nu tables, the special `explore.split_line` config point has been
retired.
2. Cell padding in tables is now controlled by `table.padding` instead
of the undocumented `column_padding_left`/`column_padding_right` config
3. The (optional, previously not enabled by default) `selected_row` and
`selected_column` configuration has been removed. We now only highlight
the selected cell. I could re-add this if people really like the feature
but I'm guessing nobody uses it.

The interface still looks the same with a default/empty config.nu:

Fix explore panic on empty lists (#13074)
This fixes up a panic I accidentally introduced when refactoring the
cursor code in `explore`: https://github.com/nushell/nushell/pull/12979

Under certain circumstances (running `:nu []`, opening `:try` with the
hidden `try.reactive` setting enabled), `explore` would panic when
handling an empty list. To fix this for now I've removed the validation
I added to the Cursor constructor in that PR.

cd/def --env examples (#13068)
# Description

Per a Discord question
(https://discord.com/channels/601130461678272522/1244293194603167845/1247794228696711198),
this adds examples to the `help` for both:

* `cd`
* `def`

to demonstrate that `def --env` is required when changing directories in
a custom command.

Since the existing examples for `def` were a bit more complex (and had
output) but the `cd` ones were more simplified, I did use slightly
different examples in each. Either or both could be tweaked if desired.

reduce log tracing in nu-cli (#13067)
This one trace message creates thousands of lines of trace messages that
is probably
better suited to using on an *as needed* basis rather than everyone
having to wade
through it...

For now, I just commented it out but eventually this line of code should
be removed
and used simply for the time when someone needs to see it...

Refactor explore cursor code (#12979)
`explore` has 3 cursor-related structs that are extensively used to
track the currently shown "window" of the data being shown. I was
finding the cursor code quite difficult to follow, so this PR:
- rewrites the base `Cursor` struct from scratch, with some tests
- makes big changes to `WindowCursor`
- renames `XYCursor` to `WindowCursor2D`
- makes some of the cursor functions fallible as a start towards better
error handling
- changes lots of function names to things that I find more intuitive
- adds comments, including ASCII diagrams to explain how the cursors
work

More work could be done (I'd like to review/change more function names
in `WindowCursor` and `WindowCursor2D` and add more tests), but this is
the limit of what I can get done in a weekend. I think this part of the
code is in a better place now.

# Testing performed

I did a lot of manual testing in the record view and binary viewer,
moving around with arrow keys / page up+down / home+end.

This can definitely wait until after the release freeze, this area has
very few automated tests and it'd be good to let the changes bake a bit.

Span ID Refactor - Step 1 (#12960)
# Description
First part of SpanID refactoring series. This PR adds a `SpanId` type
and a corresponding `span_id` field to `Expression`. Parser creating
expressions will now add them to an array in `StateWorkingSet`,
generates a corresponding ID and saves the ID to the Expression. The IDs
are not used anywhere yet.

For the rough overall plan, see
https://github.com/nushell/nushell/issues/12963.

# User-Facing Changes
Hopefully none. This is only a refactor of Nushell's internals that
shouldn't have visible side effects.

msgpackz: increase default compression level (#13035)
# Description
Increase default compression level for brotli on msgpackz to 3. This has
the best compression time generally. Level 0 and 1 give weird results
and sometimes cause extremely inflated outputs rather than being
compressed. So far this hasn't really been a problem for the plugin
registry file, but has been for other data.

The `$example` is the web-app example from https://json.org/example.html

Benchmarked with:

```nushell
seq 0 11 | each { |level|
  let compressed = ($example | to msgpackz --quality $level)
  let time = (timeit { $example | to msgpackz --quality $level })
  {
    level: $level
    time: $time
    length: ($compressed | bytes length)
    ratio: (($uncompressed_length | into float) / ($compressed | bytes length))
  }
}
```

Try to preserve the ordering of elements in from toml (#13045)
# Description

Enable the `preserve_order` feature of the `toml` crate to preserve the
ordering of elements when converting from/to toml.

Additionally, use `to_string_pretty()` instead of `to_string()` in `to
toml`. This displays arrays on multiple lines instead of one big single
line. I'm not sure if this one is a good idea or not... Happy to remove
this from this PR if it's not.

# User-Facing Changes
The order of elements will be different when using `from toml`. The
formatting of arrays will also be different when using `to toml`. For
example:

- before
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ bar │ 2 │
│ doo │ 3 │
│ foo │ 1 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = ["a", "b", "c", "d"]
```
- after
```
❯ "foo=1\nbar=2\ndoo=3" | from toml
╭─────┬───╮
│ foo │ 1 │
│ bar │ 2 │
│ doo │ 3 │
╰─────┴───╯
❯ {a: [a b c d]} | to toml
a = [
    "a",
    "b",
    "c",
    "d",
]

Fix run_external::expand_glob() to return paths that are PWD-relative but reflect the original intent (#13028)
# Description

Fix #13021

This changes the `expand_glob()` function to use
`nu_engine::glob_from()` so that absolute paths are actually preserved,
rather than being made relative to the provided parent. This preserves
the intent of whoever wrote the original path/glob, and also makes it so
that tilde always produces absolute paths.

I also made `expand_glob()` handle Ctrl-C so that it can be interrupted.

Disallow more characters in arguments for internal cmd commands (#13009)
# Description
Makes `run-external` error if arguments to `cmd.exe` internal commands
contain newlines or a percent sign. This is because the percent sign can
expand environment variables, potentially? allowing command injection.
Newlines I think will truncate the rest of the arguments and should
probably be disallowed to be safe.

# After Submitting
- If the user calls `cmd.exe` directly, then this bypasses our
handling/checking for internal `cmd` commands. Instead, we use the
handling from the Rust std lib which, in this case, does not do special
handling and is potentially unsafe. Then again, it could be the user's
specific intention to run `cmd` with whatever trusted input. The problem
is that since we use the std lib handling, it assumes the exe uses the C
runtime escaping rules and will perform some unwanted escaping. E.g., it
will add backslashes to the quotes in `cmd echo /c '""'`.
- If `cmd` is called indirectly via a `.bat` or `.cmd` file, then we use
the Rust std lib which has separate handling for bat files that should
be safe, but will reject some inputs.
- ~~I'm not sure how we handle `PATHEXT`, that can also cause a file
without an extension to be run as a bat file. If so, I don't know where
the handling, if any, is done for that.~~ It looks like we use the
`which` crate to do the lookup using `PATHEXT`. Then, we pass the exe
path from that to the Rust std lib `Command`, which should be safe
(except for the first `cmd.exe` note).

So, in the future we need to unify and/or fix these different
implementations, including our own special handling for internal `cmd`
commands that this PR tries to fix.

Restore tilde expansion on external command names (#13001)
# Description

Fix a regression introduced by #12921, where tilde expansion was no
longer done on the external command name, breaking things like

```nushell
> ~/.cargo/bin/exa
```

This properly handles quoted strings, so they don't expand:

```nushell
> ^"~/.cargo/bin/exa"
Error: nu:🐚:external_command

  × External command failed
   ╭─[entry #1:1:2]
 1 │ ^"~/.cargo/bin/exa"
   ·  ─────────┬────────
   ·           ╰── Command `~/.cargo/bin/exa` not found
   ╰────
  help: `~/.cargo/bin/exa` is neither a Nushell built-in or a known external command

```

This required a change to the parser, so the command name is also parsed
in the same way the arguments are - i.e. the quotes on the outside
remain in the expression. Hopefully that doesn't break anything else. 🤞

Fixes #13000. Should include in patch release 0.94.1

cc @YizhePKU

# User-Facing Changes
- Tilde expansion now works again for external commands
- The `command` of `run-external` will now have its quotes removed like
the other arguments if it is a literal string
- The parser is changed to include quotes in the command expression of
`ExternalCall` if they were present

# Tests + Formatting
I would like to add a regression test for this, but it's complicated
because we need a well-known binary within the home directory, which
just isn't a thing. We could drop one there, but that's kind of a bad
behavior for a test to do. I also considered changing the home directory
for the test, but that's so platform-specific - potentially could get it
working on specific platforms though. Changing `HOME` env on Linux
definitely works as far as tilde expansion works.

make polars plugin use mimalloc (#12967)
# Description
@maxim-uvarov did a ton of research and work with the dply-rs author and
ritchie from polars and found out that the allocator matters on macos
and it seems to be what was messing up the performance of polars plugin.
ritchie suggested to use jemalloc but i switched it to mimalloc to match
nushell and it seems to run better.

Do not propagate glob creation error for external args (#12955)
# Description
Instead of returning an error, this PR changes `expand_glob` in
`run_external.rs` to return the original string arg if glob creation
failed. This makes it so that, e.g.,
```nushell
^echo `[`
^echo `***`
```
no longer fail with a shell error. (This follows from #12921.)

Allow byte streams with unknown type to be compatiable with binary (#12959)
# Description
Currently, this pipeline doesn't work `open --raw file | take 100`,
since the type of the byte stream is `Unknown`, but `take` expects
`Binary` streams. This PR changes commands that expect
`ByteStreamType::Binary` to also work with `ByteStreamType::Unknown`.
This was done by adding two new methods to `ByteStreamType`:
`is_binary_coercible` and `is_string_coercible`. These return true if
the type is `Unknown` or matches the type in the method name.

Make from json --objects streaming (#12949)
# Description

Makes the `from json --objects` command produce a stream, and read
lazily from an input stream to produce its output.

Also added a helper, `PipelineData::get_type()`, to make it easier to
construct a wrong type error message when matching on `PipelineData`. I
expect checking `PipelineData` for either a string value or an `Unknown`
or `String` typed `ByteStream` will be very, very common. I would have
liked to have a helper that just returns a readable stream from either,
but that would either be a bespoke enum or a `Box<dyn BufRead>`, which
feels like it wouldn't be so great for performance. So instead, taking
the approach I did here is probably better - having a function that
accepts the `impl BufRead` and matching to use it.

# User-Facing Changes

- `from json --objects` no longer collects its input, and can be used
for large datasets or streams that produce values over time.

# Tests + Formatting
All passing.

explore cleanup: remove+move binary viewer config (#12920)
Small change, removing 4 more configuration options from `explore`'s
binary viewer:

1. `show_index`
2. `show_data`
3. `show_ascii`
4. `show_split`

These controlled whether the 3 columns in the binary viewer (index, hex
data, ASCII) and the pipe separator (`|`) in between them are shown. I
don't think we need this level of configurability until the `explore`
command is more mature, and maybe even not then; we can just show them
all.

I think it's very unlikely that anyone is using these configuration
points.

Also, the row offset (e.g. how many rows we have scrolled down) was
being stored in config/settings when it's arguably not config; more like
internal state of the binary viewer. I moved it to a more appropriate
location and renamed it.

Rewrite run_external.rs (#12921)
This PR is a complete rewrite of `run_external.rs`. The main goal of the
rewrite is improving readability, but it also fixes some bugs related to
argument handling and the PATH variable (fixes
https://github.com/nushell/nushell/issues/6011).

I'll discuss some technical details to make reviewing easier.

## Argument handling

Quoting arguments for external commands is hard. Like, *really* hard.
We've had more than a dozen issues and PRs dedicated to quoting
arguments (see Appendix) but the current implementation is still buggy.

Here's a demonstration of the buggy behavior:

```nu
let foo = "'bar'"
^touch $foo            # This creates a file named `bar`, but it should be `'bar'`
^touch ...[ "'bar'" ]  # Same
```

I'll describe how this PR deals with argument handling.

First, we'll introduce the concept of **bare strings**. Bare strings are
**string literals** that are either **unquoted** or **quoted by
backticks** [^1]. Strings within a list literal are NOT considered bare
strings, even if they are unquoted or quoted by backticks.

When a bare string is used as an argument to external process, we need
to perform tilde-expansion, glob-expansion, and inner-quotes-removal, in
that order. "Inner-quotes-removal" means transforming from
`--option="value"` into `--option=value`.

## `.bat` files and CMD built-ins

On Windows, `.bat` files and `.cmd` files are considered executable, but
they need `CMD.exe` as the interpreter. The Rust standard library
supports running `.bat` files directly and will spawn `CMD.exe` under
the hood (see
[documentation](https://doc.rust-lang.org/std/process/index.html#windows-argument-splitting)).
However, other extensions are not supported [^2].

Nushell also supports a selected number of CMD built-ins. The problem
with CMD is that it uses a different set of quoting rules. Correctly
quoting for CMD requires using
[Command::raw_arg()](https://doc.rust-lang.org/std/os/windows/process/trait.CommandExt.html#tymethod.raw_arg)
and manually quoting CMD special characters, on top of quoting from the
Nushell side. ~~I decided that this is too complex and chose to reject
special characters in CMD built-ins instead [^3]. Hopefully this will
not affact real-world use cases.~~ I've implemented escaping that works
reasonably well.

## `which-support` feature

The `which` crate is now a hard dependency of `nu-command`, making the
`which-support` feature essentially useless. The `which` crate is
already a hard dependency of `nu-cli`, and we should consider removing
the `which-support` feature entirely.

## Appendix

Here's a list of quoting-related issues and PRs in rough chronological
order.

* https://github.com/nushell/nushell/issues/4609
* https://github.com/nushell/nushell/issues/4631

[^1]: The idea that backtick-quoted strings act like bare strings was
introduced by Kubouch and briefly mentioned in [the language
reference](https://www.nushell.sh/lang-guide/chapters/strings_and_text.html#backtick-quotes).

[^2]: The documentation also said "running .bat scripts in this way may
be removed in the future and so should not be relied upon", which is
another reason to move away from this. But again, quoting for CMD is
hard.

[^3]: If anyone wants to try, the best resource I found on the topic is
[this](https://daviddeley.com/autohotkey/parameters/parameters.htm).

Implement streaming I/O for CSV and TSV commands (#12918)
# Description

Implements streaming for:

- `from csv`
- `from tsv`
- `to csv`
- `to tsv`

via the new string-typed ByteStream support.

# User-Facing Changes
Commands above. Also:

- `to csv` and `to tsv` now have `--columns <List(String)>`, to provide
the exact columns desired in the output. This is required for them to
have streaming output, because otherwise collecting the entire list is
necessary to determine the output columns. If we introduce
`TableStream`, this may become less necessary.

Add support for the ps command on FreeBSD, NetBSD, and OpenBSD (#12892)
# Description

I feel like it's a little sad that BSDs get to enjoy almost everything
other than the `ps` command, and there are some tests that rely on this
command, so I figured it would be fun to patch that and make it work.

The different BSDs have diverged from each other somewhat, but generally
have a similar enough API for reading process information via
`sysctl()`, with some slightly different args.

This supports FreeBSD with the `freebsd` module, and NetBSD and OpenBSD
with the `netbsd` module. OpenBSD is a fork of NetBSD and the interface
has some minor differences but many things are the same.

I had wanted to try to support DragonFlyBSD too, but their Rust version
in the latest release is only 1.72.0, which is too old for me to want to
try to compile rustc up to 1.77.2... but I will revisit this whenever
they do update it. Dragonfly is a fork of FreeBSD, so it's likely to be
more or less the same - I just don't want to enable it without testing
it.

Fixes #6862 (partially, we probably won't be adding `zfs list`)

# User-Facing Changes
`ps` added for FreeBSD, NetBSD, and OpenBSD.

# Tests + Formatting
The CI doesn't run tests for BSDs, so I'm not entirely sure if
everything was already passing before. (Frankly, it's unlikely.) But
nothing appears to be broken.

# After Submitting
- [ ] release notes?
- [ ] DragonflyBSD, whenever they do update Rust to something close
enough for me to try it

Add completer for std help (#12929)

explore: consolidate padding config, handle ByteStream, tweak naming+comments (#12915)
Some minor changes to `explore`, continuing on my mission to simplify
the command in preparation for a larger UX overhaul:

1. Consolidate padding configuration. I don't think we need separate
config points for the (optional) index column and regular data columns
in the normal pager, they can share padding configuration. Likewise, in
the binary viewer all 3 columns (index, data, ASCII) had their
left+right padding configured independently.
2. Update `explore` so we use the binary viewer for the new `ByteStream`
type. `cat foo.txt | into binary | explore` was not using the binary
viewer after the `ByteStream` changes.
3. Tweak the naming of a few helper functions, add a comment

I've put the changes in separate commits to make them easier to review.

Add string/binary type color to ByteStream (#12897)
# Description

This PR allows byte streams to optionally be colored as being
specifically binary or string data, which guarantees that they'll be
converted to `Binary` or `String` appropriately on `into_value()`,
making them compatible with `Type` guarantees. This makes them
significantly more broadly usable for command input and output.

There is still an `Unknown` type for byte streams coming from external
commands, which uses the same behavior as we previously did where it's a
string if it's UTF-8.

A small number of commands were updated to take advantage of this, just
to prove the point. I will be adding more after this merges.

# User-Facing Changes
- New types in `describe`: `string (stream)`, `binary (stream)`
- These commands now return a stream if their input was a stream:
  - `into binary`
  - `into string`
  - `bytes collect`
  - `str join`
  - `first` (binary)
  - `last` (binary)
  - `take` (binary)
  - `skip` (binary)
- Streams that are explicitly binary colored will print as a streaming
hexdump
  - example:
    ```nushell
    1.. | each { into binary } | bytes collect
    ```

# Tests + Formatting
I've added some tests to cover it at a basic level, and it doesn't break
anything existing, but I do think more would be nice. Some of those will
come when I modify more commands to stream.

# After Submitting
There are a few things I'm not quite satisfied with:

- **String trimming behavior.** We automatically trim newlines from
streams from external commands, but I don't think we should do this with
internal commands. If I call a command that happens to turn my string
into a stream, I don't want the newline to suddenly disappear. I changed
this to specifically do it only on `Child` and `File`, but I don't know
if this is quite right, and maybe we should bring back the old flag for
`trim_end_newline`
- **Known binary always resulting in a hexdump.** It would be nice to
have a `print --raw`, so that we can put binary data on stdout
explicitly if we want to. This PR doesn't change how external commands
work though - they still dump straight to stdout.

Otherwise, here's the normal checklist:

- [ ] release notes
- [ ] docs update for plugin protocol changes (added `type` field)

Make get_full_help take &dyn Command (#12903)
# Description
Changes `get_full_help` to take a `&dyn Command` instead of multiple
arguments (`&Signature`, `&Examples` `is_parser_keyword`). All of these
arguments can be gathered from a `Command`, so there is no need to pass
the pieces to `get_full_help`.

`--help` is used on a command.

Use CommandType in more places (#12832)
# Description
Kind of a vague title, but this PR does two main things:
1. Rather than overriding functions like `Command::is_parser_keyword`,
this PR instead changes commands to override `Command::command_type`.
The `CommandType` returned by `Command::command_type` is then used to
automatically determine whether `Command::is_parser_keyword` and the
other `is_{type}` functions should return true. These changes allow us
to remove the `CommandType::Other` case and should also guarantee than
only one of the `is_{type}` functions on `Command` will return true.
2. Uses the new, reworked `Command::command_type` function in the `scope
commands` and `which` commands.


# User-Facing Changes
- Breaking change for `scope commands`: multiple columns (`is_builtin`,
`is_keyword`, `is_plugin`, etc.) have been merged into the `type`
column.
- Breaking change: the `which` command can now report `plugin` or
`keyword` instead of `built-in` in the `type` column. It may also now
report `external` instead of `custom` in the `type` column for known
`extern`s.

Preserve metadata in more places (#12848)
# Description
This PR makes some commands and areas of code preserve pipeline
metadata. This is in an attempt to make the issue described in #12599
and #9456 less likely to occur. That is, reading and writing to the same
file in a pipeline will result in an empty file. Since we preserve
metadata in more places now, there will be a higher chance that we
successfully detect this error case and abort the pipeline.

collect: don't require a closure (#12788)
# Description

This changes the `collect` command so that it doesn't require a closure.
Still allowed, optionally.

Before:

```nushell
open foo.json | insert foo bar | collect { save -f foo.json }
```

After:

```nushell
open foo.json | insert foo bar | collect | save -f foo.json
```

The closure argument isn't really necessary, as collect values are also
supported as `PipelineData`.

# User-Facing Changes
- `collect` command changed

# Tests + Formatting
Example changed to reflect.

# After Submitting
- [ ] release notes
- [ ] we may want to deprecate the closure arg?

Fix the way the output of table is printed in print() (#12895)
# Description

Forgot that I fixed this already on my branch, but when printing without
a display output hook, the implicit call to `table` gets its output

allow define it as a variable inside closure (#12888)
# Description
Fixes: #12690 

The issue is happened after
https://github.com/nushell/nushell/pull/12056 is merged. It will raise
error if user doesn't supply required parameter when run closure with
do.
And parser adds a `$it` parameter when parsing closure or block
expression.

I believe the previous behavior is because we allow such syntax on
previous version(0.44):
```nushell
let x = { print $it }
```
But it's no longer allowed after 0.60.  So I think they can be removed.

# User-Facing Changes
```nushell
let tmp = {
  let it = 42
  print $it
}

do -c $tmp
```
should be possible again.

Add Span merging functions (#12511)
# Description
This PR adds a few functions to `Span` for merging spans together:
- `Span::append`: merges two spans that are known to be in order.
- `Span::concat`: returns a span that encompasses all the spans in a
slice. The spans must be in order.
- `Span::merge`: merges two spans (no order necessary).
- `Span::merge_many`: merges an iterator of spans into a single span (no
order necessary).

These are meant to replace the free-standing `nu_protocol::span`
function.

The spans in a `LiteCommand` (the `parts`) should always be in order
based on the lite parser and lexer. So, the parser code sees the most
usage of `Span::append` and `Span::concat` where the order is known. In
other code areas, `Span::merge` and `Span::merge_many` are used since
the order between spans is often not known.

Replace ExternalStream with new ByteStream type (#12774)
# Description
This PR introduces a `ByteStream` type which is a `Read`-able stream of
bytes. Internally, it has an enum over three different byte stream
sources:
```rust
pub enum ByteStreamSource {
    Read(Box<dyn Read + Send + 'static>),
    File(File),
    Child(ChildProcess),
}
```

This is in comparison to the current `RawStream` type, which is an
`Iterator<Item = Vec<u8>>` and has to allocate for each read chunk.

Currently, `PipelineData::ExternalStream` serves a weird dual role where
it is either external command output or a wrapper around `RawStream`.
`ByteStream` makes this distinction more clear (via `ByteStreamSource`)
and replaces `PipelineData::ExternalStream` in this PR:
```rust
pub enum PipelineData {
    Empty,
    Value(Value, Option<PipelineMetadata>),
    ListStream(ListStream, Option<PipelineMetadata>),
    ByteStream(ByteStream, Option<PipelineMetadata>),
}
```

The PR is relatively large, but a decent amount of it is just repetitive
changes.

This PR fixes #7017, fixes #10763, and fixes #12369.

This PR also improves performance when piping external commands. Nushell
should, in most cases, have competitive pipeline throughput compared to,
e.g., bash.
| Command | Before (MB/s) | After (MB/s) | Bash (MB/s) |
| -------------------------------------------------- | -------------:|
------------:| -----------:|
| `throughput \| rg 'x'` | 3059 | 3744 | 3739 |
| `throughput \| nu --testbin relay o> /dev/null` | 3508 | 8087 | 8136 |

# User-Facing Changes
- This is a breaking change for the plugin communication protocol,
because the `ExternalStreamInfo` was replaced with `ByteStreamInfo`.
Plugins now only have to deal with a single input stream, as opposed to
the previous three streams: stdout, stderr, and exit code.
- The output of `describe` has been changed for external/byte streams.
- Temporary breaking change: `bytes starts-with` no longer works with
byte streams. This is to keep the PR smaller, and `bytes ends-with`
already does not work on byte streams.
- If a process core dumped, then instead of having a `Value::Error` in
the `exit_code` column of the output returned from `complete`, it now is
a `Value::Int` with the negation of the signal number.

# After Submitting
- Update docs and book as necessary
- Release notes (e.g., plugin protocol changes)
- Adapt/convert commands to work with byte streams (high priority is
`str length`, `bytes starts-with`, and maybe `bytes ends-with`).
- Refactor the `tee` code, Devyn has already done some work on this.

Remove stack debug assert (#12861)
# Description
In order for `Stack::unwrap_unique` to work as intended, we currently
manually track all references to the parent stack and ensure that they
are cleared before calling `Stack::unwrap_unique` in the REPL. We also
only call `Stack::unwrap_unique` after all code from the current REPL
entry has finished executing. Since `Value`s cannot store `Stack`
references, then this should have worked in theory. However, we forgot
to account for threads. `run-external` (and maybe the plugin writers)
can spawn threads that clone the `Stack`, holding on to references of
the parent stack. These threads are not waited/joined upon, and so may
finish after the eval has already returned. This PR removes the
`Stack::unwrap_unique` function and associated debug assert that was
[causing
panics](https://gist.github.com/cablehead/f3d2608a1629e607c2d75290829354f7)
like @cablehead found.

# After Submitting

performance issues with cloning the stack.

make better messages for incomplete string (#12868)
# Description
Fixes: #12795

The issue is caused by an empty position of `ParseError::UnexpectedEof`.
So no detailed message is displayed.
To fix the issue, I adjust the start of span to `span.end - 1`. In this
way, we can make sure that it never points to an empty position.

After lexing item, I also reorder the unclosed character checking . Now
it will be checking unclosed opening delimiters first.
