remove content_type metadata from pipeline after from ... commands (#14602)
# Description

`from ...` conversions pass along all metadata except `content_type`,
which they set to `None`.

## Rationale

`open`ing a file results in no `content_type` metadata if it can be
parsed into a nu data structure, and using `open --raw` results in
`content_type` metadata.

`from ...` commands should preserve metadata ***except*** for
`content_type`, as after parsing it's no longer that `content_type` and
just structured nu data.

These commands should return identical data *and* identical metadata

```nushell
open foo.csv
```

```nushell
open foo.csv --raw | from csv
```

remove the deprecated index argument from filter commands' closure signature (#14594)
# Description

A lot of filter commands that have a closure argument (`each`, `filter`,
etc), have a wrong signature for the closure, indicating an extra int
argument for the closure.

I think they are a left over from before `enumerate` was added, used to
access iteration index. None of the commands changed in this PR actually
supply this int argument.

fixes #14567

Now NuShell's `exec` command will decrement `SHLVL` env value before
passing it to target executable.

It only works in interactive session, the same as `SHLVL`
initialization.

In addition, this PR also make a simple change to `SHLVL` initialization
(only remove an unnecessary type conversion).

du: add -l/--long flag, remove -a/--all flag (#14407)
# Description
Closes:  #14387 
~To make it happen, just need to added `-l` flag to `du`, and pass it to
`DirBuilder`, `DirInfo`, `FileInfo`
Then tweak `impl From<DirInfo> for Value` and `impl From<FileInfo> for
Value` impl.~

---

Edit: this PR is going to:
1. Exclude directories and files columns by default
2. Added `-l/--long` flag to output directories and files columns
3. When running `du`, it will output the files as well. Previously it
doesn't output the size of file.

To make it happen, just need to added `-r` flag to `du`, and pass it to
`DirBuilder`, `DirInfo`, `FileInfo`
Then tweak `impl From<DirInfo> for Value` and `impl From<FileInfo> for
Value` impl.

And rename some variables.

# User-Facing Changes
`du` is no longer output `directories` and `file` columns by default,
added `-r` flag will show `directories` column, `-f` flag will show
`files` column.

Change help commands to use name from scope instead of the name from the declaration (#14490)
# Description

Before this PR, `help commands` uses the name from a command's
declaration rather than the name in the scope. This is problematic when
trying to view the help page for the `main` command of a module. For
example, `std bench`:

```nushell
use std/bench
help bench
# => Error: nu::parser::not_found
# => 
# =>   × Not found.
# =>    ╭─[entry #10:1:6]
# =>  1 │ help bench
# =>    ·      ──┬──
# =>    ·        ╰── did not find anything under this name
# =>    ╰────
```

This can also cause confusion when importing specific commands from
modules. Furthermore, if there are multiple commands with the same name
from different modules, the help text for _both_ will appear when
querying their help text (this is especially problematic for `main`
commands, see #14033):

```nushell
use std/iter
help iter find
# => Error: nu::parser::not_found
# => 
# =>   × Not found.
# =>    ╭─[entry #3:1:6]
# =>  1│ help iter find
# =>    ·      ────┬────
# =>    ·          ╰── did not find anything under this name
# =>    ╰────
help find
# => Searches terms in the input.
# => 
# => Search terms: filter, regex, search, condition
# => 
# => Usage:
# =>   > find {flags} ...(rest) 
# [...]
# => Returns the first element of the list that matches the
# => closure predicate, `null` otherwise
# [...]
# (full text omitted for brevity)
```

This PR changes `help commands` to use the name as it is in scope, so
prefixing any command in scope with `help` will show the correct help
text.


```nushell
use std/bench
help bench
# [help text for std bench]
use std/iter
help iter find
# [help text for std iter find]

use std
help std bench
# [help text for std bench]
help std iter find
# [help text for std iter find]
```

Additionally, the IR code generation for commands called with the
`--help` text has been updated to reflect this change.

This does have one side effect: when a module has a `main` command
defined, running `help <name>` (which checks `help aliases`, then `help
commands`, then `help modules`) will show the help text for the `main`
command rather than the module. The help text for the module is still
accessible with `help modules <name>`.

Fixes #10499, #10311, #11609, #13470, #14033, and #14402.
Partially fixes #10707.
Does **not** fix #11447.

# User-Facing Changes

* Help text for commands can be obtained by running `help <command
name>`, where the command name is the same thing you would type in order
to execute the command. Previously, it was the name of the function as
written in the source file.
  * For example, for the following module `spam` with command `meow`:
    ```nushell
    module spam { 
        # help text
        export def meow [] {}
    }
    ```
    * Before this PR:
* Regardless of how `meow` is `use`d, the help text is viewable by
running `help meow`.
    * After this PR:
* When imported with `use spam`: The `meow` command is executed by
running `spam meow` and the `help` text is viewable by running `help
spam meow`.
* When imported with `use spam foo`: The `meow` command is executed by
running `meow` and the `help` text is viewable by running `meow`.
* When a module has a `main` command defined, `help <module name>` will
return help for the main command, rather than the module. To access the
help for the module, use `help modules <module name>`.

Make timeit take only closures as an argument (#14483)
# Description

Fixes #14401 where expressions passed to `timeit` will execute twice.
This PR removes the expression support for `timeit`, as this behavior is
almost exclusive to `timeit` and can hinder migration to the IR
evaluator in the future. Additionally, `timeit` used to be able to take
a `block` as an argument. Blocks should probably only be allowed for
parser keywords, so this PR changes `timeit` to instead only take
closures as an argument. This also fixes an issue where environment
updates inside the `timeit` block would affect the parent scope and all
commands later in the pipeline.

```nu
> timeit { $env.FOO = 'bar' }; print $env.FOO
bar
```

# User-Facing Changes

`timeit` now only takes a closure as the first argument.

Update examples in the book/docs if necessary.

In this PR I made the `cwd` parameter in the functions from the `table`
command not used when targeting `not(feature = "os)`. As without an OS
and therefore without filesystem we don't have any real concept of a
current working directory. This allows using the `table` command in the
WASM context.

Add path self command for getting absolute paths to files at parse time (#14303)
Alternative solution to:
- #12195 

The other approach:
- #14305

# Description
Adds ~`path const`~ `path self`, a parse-time only command for getting
the absolute path of the source file containing it, or any file relative
to the source file.

- Useful for any script or module that makes use of non nuscript files.
- Removes the need for `$env.CURRENT_FILE` and `$env.FILE_PWD`.
- Can be used in modules, sourced files or scripts.

# Examples

```nushell
# ~/.config/nushell/scripts/foo.nu
const paths = {
    self: (path self),
    dir: (path self .),
    sibling: (path self sibling),
    parent_dir: (path self ..),
    cousin: (path self ../cousin),
}

export def main [] {
    $paths
}
```

```nushell
> use foo.nu
> foo
╭────────────┬────────────────────────────────────────────╮
│ self       │ /home/user/.config/nushell/scripts/foo.nu  │
│ dir        │ /home/user/.config/nushell/scripts         │
│ sibling    │ /home/user/.config/nushell/scripts/sibling │
│ parent_dir │ /home/user/.config/nushell                 │
│ cousin     │ /home/user/.config/nushell/cousin          │
╰────────────┴────────────────────────────────────────────╯
```


Trying to run in a non-const context
```nushell
> path self
Error:   × this command can only run during parse-time
   ╭─[entry #1:1:1]
 1 │ path self 
   · ─────┬────
   ·      ╰── can't run after parse-time
   ╰────
  help: try assigning this command's output to a const variable
```

Trying to run in the REPL i.e. not in a file
```nushell
> const foo = path self
Error:   × Error: nu:🐚:file_not_found
  │ 
  │   × File not found
  │    ╭─[entry #3:1:13]
  │  1 │ const foo = path self
  │    ·             ─────┬────
  │    ·                  ╰── Couldn't find current file
  │    ╰────
  │ 
   ╭─[entry #3:1:13]
 1 │ const foo = path self
   ·             ─────┬────
   ·                  ╰── Encountered error during parse-time evaluation
   ╰────
```

# Comparison with #14305
## Pros
- Self contained implementation, does not require changes in the parser.
- More concise usage, especially with parent directories.

allow select to stream more (#14492)
# Description

closes https://github.com/nushell/nushell/issues/14487

This PR tries to allow the `select` to stream better by changing the for
loops that collected the output into a `Vec<Value>` prior to returning
it into a map that returns the data as it is processed.

One curiosity, `select` transforms the input into a `PipelineIterator`.
If I remove this code, it still passes all tests. I'm not sure all this
`PipelineIterator` code is even needed. I left it for someone to tell me
if it's necessary.

Feature: PWD-per-drive to facilitate working on multiple drives at Windows (#14411)
This PR implements PWD-per-drive as described in discussion #14355

# Description
On Windows, CMD or PowerShell assigns each drive its own current
directory. For example, if you are in 'C:\Windows', switch to 'D:', and
navigate to 'D:\Game', you can return to 'C:\Windows' by simply typing
'C:'.

This PR enables Nushell on Windows to have the same capability, allowing
each drive to maintain its own PWD (Present Working Directory).

# User-Facing Changes
Currently, 'cd' or 'ls' only accept absolute paths if the path starts
with 'C:' or another drive letter. With PWD-per-drive, users can use
'cd' (or auto cd) and 'ls' in the same way as 'cd' and 'dir' in
PowerShell, or similarly to 'cd' and 'dir' in CMD (noting that cd in CMD
has slightly different behavior, 'cd' for another drive only changes
current directory of that drive, but does not switch there).

Interaction example on switching between drives:
```Nushell
~>D:
D:\>cd Test
D:\Test\>C:

# Brief Change Description
 
1.Added 'crates/nu-path/src/pwd_per_drive.rs' to implement a 26-slot
array mapping drive letters to PWDs. Test cases are included in the same
file, along with a doctest for the usage of PWD-per-drive.
2. Modified 'crates/nu-path/src/lib.rs' to declare module of
pwd_per_drive and export struct for PWD-per-drive.
3. Modified 'crates/nu-protocol/src/engine/stack.rs' to sync PWD when
set_cwd() is called. Add PWD-per-drive map as member. Clone between
parent and child. Stub/proxy for nu_path::expand_path_with() to
facilitate filesystem commands using PWD-per-drive.
4. Modified 'crates/nu-cli/src/repl.rs' auto_cd uses PWD-per-drive to
expand path.
5. Modified 'crates/nu-cli/src/completions/completion_common.rs' to
expand relative path when press [TAB] at command line.
6. Modified 'crates/nu-engine/src/env.rs' to collect PWD-per-drive info
as env vars for child process as CMD or PowerShell do, this can let
child process inherit PWD-per-drive info.
7. Modified 'crates/nu-engine/src/eval.rs', caller clone callee's
PWD-per-drive info, supporting 'def --env'
8. Modified 'crates/nu-engine/src/eval_ir.rs', 'def --env' support.
Remove duplicated fn redirect_env()
9. Modified 'src/run.rs', to init PWD-per-drive when startup.

filesystem commands that modified:
1. Modified 'crates/nu-command/src/filesystem/cd.rs', 1 line change to
use stackscoped PWD-per-drive.
Other commands, commit pending....

Local test def --env OK:

Add environment variables for sourced files (#14486)
# Description

I always wondered why the module env vars `CURRENT_FILE`, `FILE_PWD`,
`PROCESS_PATH` weren't available in the source command. I tried to add
them here. I think it could be helpful but I'm not sure. I'm also not
sure this hack is what we should do but I thought I'd put it out there
for fun.

Thoughts?

### Run Module (works as it did before)

```nushell
❯ open test_module.nu
def main [] {
  print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
  print $"$env.FILE_PWD = ($env.FILE_PWD?)"
  print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
}
❯ nu test_module.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_module.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH = test_module.nu
```
### Use Module (works as it did before)
```nushell
❯ open test_module2.nu
export-env {
  print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
  print $"$env.FILE_PWD = ($env.FILE_PWD?)"
  print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
}
❯ use test_module2.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_module.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH =
```
### Sourced non-module script (this is the new part)

> [!NOTE] 
> Note: We intentionally left out PROCESS_PATH since it's supposed to
> to work like argv[0] in C, which is the name of the program being
executed.
> Since we're not executing a program, we don't need to set it.


```nushell
❯ open test_source.nu
print $"$env.CURRENT_FILE = ($env.CURRENT_FILE?)"
print $"$env.FILE_PWD = ($env.FILE_PWD?)"
print $"$env.PROCESS_PATH = ($env.PROCESS_PATH?)"
❯ source test_source.nu
$env.CURRENT_FILE = /Users/fdncred/src/nushell/test_source.nu
$env.FILE_PWD = /Users/fdncred/src/nushell
$env.PROCESS_PATH = 
```

Also, what is PROCESS_PATH even supposed to be?

term query: refactor, add --beginning flag (#14446)
# Description

- Refactor code to be simpler.
- Make the mentioned changes.
- `scopeguard` is added as a direct dependency. Helps simplify the code.
Rather than roll an ad-hoc version of it myself, I thought it would be
better to use `scopeguard` as it was already an indirect dependency.

# User-Facing Changes

- Add `--beginning` flag, which is used to validate the response and
provide early errors in case of unexpected inputs.
- Both `terminator` and `beginning` sequences (when provided) are not
included in the command's output. Turns out they are almost always
removed from the output, and because they are known beforehand they can
be added back by the user.

Add --long flag for sys cpu (#14485)
# Description

Fixes #14470 where the `sys cpu` command is slow. This was done by
removing the `cpu_usage` column from the default output, since it takes
400ms to calculate. Instead a `--long` flag was added that, when
provided, adds back the `cpu_usage` column.

```nu
# Before
> bench { sys cpu | length } | get mean
401ms 591µs 896ns

# After
> bench { sys cpu | length } | get mean
500µs 13ns # around 1-2ms in practice
```

# User-Facing Changes

- `sys cpu` no longer has a `cpu_usage` column by default.
- Added  a `--long` flag for `sys cpu` to add back the removed column.

# Description
<!--
Thank you for improving Nushell. Please, check our [contributing
guide](../CONTRIBUTING.md) and talk to the core team before making major
changes.

Description of your pull request goes here. **Provide examples and/or
screenshots** if your changes affect the user experience.
-->
The [nushell/demo](https://github.com/nushell/demo) project successfully
demonstrated running Nushell in the browser using WASM. However, the
current version of Nushell cannot be easily built for the
`wasm32-unknown-unknown` target, the default for `wasm-bindgen`.

This PR introduces initial support for the `wasm32-unknown-unknown`
target by disabling OS-dependent features such as filesystem access, IO,
and platform/system-specific functionality. This separation is achieved
using a new `os` feature in the following crates:

 - `nu-cmd-lang`
 - `nu-command`
 - `nu-engine`
 - `nu-protocol`

The `os` feature includes all functionality that interacts with an
operating system. It is enabled by default, but can be disabled using
`--no-default-features`. All crates that depend on these core crates now
use `--no-default-features` to allow compilation for WASM.

To demonstrate compatibility, the following script builds all crates
expected to work with WASM. Direct user interaction, running external
commands, working with plugins, and features requiring `openssl` are out
of scope for now due to their complexity or reliance on C libraries,
which are difficult to compile and link in a WASM environment.

```nushell
[ # compatible crates
	"nu-cmd-base",
	"nu-cmd-extra",
	"nu-cmd-lang",
	"nu-color-config",
	"nu-command",
	"nu-derive-value",
	"nu-engine",
	"nu-glob",
	"nu-json",
	"nu-parser",
	"nu-path",
	"nu-pretty-hex",
	"nu-protocol",
	"nu-std",
	"nu-system",
	"nu-table",
	"nu-term-grid",
	"nu-utils",
	"nuon"
] | each {cargo build -p $in --target wasm32-unknown-unknown --no-default-features}
```

## Caveats
This PR has a few caveats:
1. **`miette` and `terminal-size` Dependency Issue**
`miette` depends on `terminal-size`, which uses `rustix` when the target
is not Windows. However, `rustix` requires `std::os::unix`, which is
unavailable in WASM. To address this, I opened a
[PR](https://github.com/eminence/terminal-size/pull/68) for
`terminal-size` to conditionally compile `rustix` only when the target
is Unix. For now, the `Cargo.toml` includes patches to:
    - Use my forked version of `terminal-size`.
- ~~Use an unreleased version of `miette` that depends on
`terminal-size@0.4`.~~

These patches are temporary and can be removed once the upstream changes
are merged and released.

2. **Test Output Adjustments**
Due to the slight bump in the `miette` version, one test required
adjustments to accommodate minor formatting changes in the error output,
such as shifted newlines.

# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
This shouldn't break anything but allows using some crates for targeting
`wasm32-unknown-unknown` to revive the demo page eventually.

# Tests + Formatting

Deprecate date to-record and date to-table (#14319)
# Description

Implements #11234 based on the comments there:

* (Previously implemented): `into record` handles nanoseconds (as well
as milliseconds and microseconds, which the deprecated commands didn't
support).
* Added deprecation warning to `date to-record` and `date to-table`
* Added new example for `into record` showing the conversion to a table
* Changed `std/dt` to use `into record`
* Added "Deprecated" category back to nu-protocol::Signature
* Assigned the deprecated commands to the Deprecated category so be
categorized properly in the online Doc.

# User-Facing Changes

# After Submitting

Searched doc for existing uses of `date to-record` and `date to-table`:

* For primary English-language docs, there are no uses other than in the
auto-generated command help, which will be updated based on this PR
* Other language translations appear to have an old use in several
places and will need to be updated to match the English-language doc.

raise ParseError if assign to a non-variable or non-mutable-variable (#14405)
# Description
While reviewing #14388, I think we can make some improvement on parser.

For the following code:
```nushell
let a = 3
a = 10   # should be error
$a = 10 # another error
```
I think they can raise `ParseError`, so nushell doesn't need to move
forward compiling IR block.

# User-Facing Changes
```nushell
let a = 3
a = 10
```
Will raise parse error instead of compile error.

Add Filesize type (#14369)
# Description
Adds a new `Filesize` type so that `FromValue` can be used to convert a
`Value::Filesize` to a `Filesize`. Currently, to extract a filesize from
a `Value` using `FromValue`, you have to extract an `i64` which coerces
`Value::Int`, `Value::Duration`, and `Value::Filesize` to an `i64`.

Having a separate type also allows us to enforce checked math to catch
overflows. Similarly, it allows us to specify other trait
implementations like `Display` in a common place.

# User-Facing Changes
Multiplication with filesizes now error on overflow. Should not be a
breaking change for plugins (i.e., serialization) since `Filesize` is
marked with `serde(transparent)`.

# Tests + Formatting
Updated some tests.

Make length only operate on supported input types (#14475)
# Description


Before this PR, `length` did not check its input type at run-time, so it
would attempt to calculate a length for any input with indeterminate
type (e.g., `echo` which has an `any` output type). This PR makes
`length` only work on the types specifically supported in its
input/output types (list/table, binary, and nothing), making the
behavior the same at parse-time and at run-time.

Fixes #14462

# User-Facing Changes


Length will error if passed an unsupported type:

Before (only caught at parse-time):
```nushell
"hello" | length
Error: nu::parser::input_type_mismatch

  × Command does not support string input.
   ╭─[entry #2:1:11]

```

After (caught at parse-time and run-time):
```nushell

update unicode-width to 0.2 (#14456)
# Description
When looking into #14395, I found that `unicode-width` from 0.1 to 0.2
contains a breaking change, the mainly change is it treats newlines as
width 1. So relative tests(str stats) are broken.
But I think it's ok to adjust the test.

# User-Facing Changes
The output of `str stats` might change if there are `\n` in the input.
### Before

Add term query, for querying information from terminals. (#14427)

- #10387
- https://github.com/nushell/nushell/pull/10387#issuecomment-1722228185

# Description
`term query`: a command for querying information from the terminal.

Prints the `$query`, and immediately starts reading raw bytes from
stdin.

The standard input will be read until the `terminator` sequence is
encountered.
The `terminator` is not removed from the output.

It also stops on <kbd>Ctrl-C</kbd> with an error.

```
Usage:
  > term query {flags} <query> 

Flags:
  -h, --help: Display the help message for this command
  -t, --terminator (required parameter) <one_of(binary, string)>: stdin will be read until this sequence is encountered

Parameters:
  query <one_of(binary, string)>: The query that will be printed to stdout
```

This was previously possible with `input` until #10150.
`input` command's features such as cursor control, deleting input etc.
are useful, but interfere with this use case.

`term query` makes the following uses possible:

```nushell
# get the terminal size with ansi escape codes
def terminal-size [] {
    let response = term query (ansi size) --terminator 'R'

Change append operator to concatenation operator (#14344)
# Description

The "append" operator currently serves as both the append operator and
the concatenation operator. This dual role creates ambiguity when
operating on nested lists.

```nu
[1 2] ++ 3     # appends a value to a list [1 2 3]
[1 2] ++ [3 4] # concatenates two lists    [1 2 3 4]

[[1 2] [3 4]] ++ [5 6]
# does this give [[1 2] [3 4] [5 6]]
# or             [[1 2] [3 4] 5 6]  
```

Another problem is that `++=` can change the type of a variable:
```nu
mut str = 'hello '
$str ++= ['world']
($str | describe) == list<string>
```

Note that appending is only relevant for lists, but concatenation is
relevant for lists, strings, and binary values. Additionally, appending
can be expressed in terms of concatenation (see example below). So, this
PR changes the `++` operator to only perform concatenation.

# User-Facing Changes

Using the `++` operator with a list and a non-list value will now be a
compile time or runtime error.
```nu
mut list = []
$list ++= 1 # error
```
Instead, concatenate a list with one element:
```nu
$list ++= [1]
```
Or use `append`:
```nu
$list = $list | append 1
```

# After Submitting

Update book and docs.

remove terminal_size crate everywhere it makes sense (#14423)
# Description

This PR removes the `terminal_size` crate everywhere that it made sense.
I replaced it with crossterm's version called `size`. The places I
didn't remove it were the places that did not have a dependency on
crossterm. So, I thought it was "cheaper" to have a dep on term_size vs
crossterm in those locations.

truly flexible csv/tsv parsing (#14399)
- fixes #14398

I will properly fill out this PR and fix any tests that might break when
I have the time, this was a quick fix.

# Description

This PR makes `from csv` and `from tsv`, with the `--flexible` flag,
stop dropping extra/unexpected columns.

# User-Facing Changes

`$text`'s contents
```csv
value
1,aaa
2,bbb
3
4,ddd
5,eee,extra
```

Old behavior
```nushell
> $text | from csv --flexible --noheaders 
╭─#─┬─column0─╮
│ 0 │ value   │
│ 1 │       1 │
│ 2 │       2 │
│ 3 │       3 │
│ 4 │       4 │
│ 5 │       5 │
╰─#─┴─column0─╯
```

New behavior
```nushell
> $text | from csv --flexible --noheaders 
╭─#─┬─column0─┬─column1─┬─column2─╮
│ 0 │ value   │       │
│ 1 │       1 │ aaa     │       │
│ 2 │       2 │ bbb     │       │
│ 3 │       3 │       │
│ 4 │       4 │ ddd     │       │
│ 5 │       5 │ eee     │ extra   │
╰─#─┴─column0─┴─column1─┴─column2─╯
```

- The first line in a csv (or tsv) document no longer limits the number
of columns
- Missing values in columns are longer automatically filled with `null`
with this change, as a later row can introduce new columns. **BREAKING
CHANGE**

Because missing columns are different from empty columns, operations on
possibly missing columns will have to use optional access syntax e.g.
`get foo` => `get foo?`
  
# Tests + Formatting
Added examples that run as tests and adjusted existing tests to confirm
the new behavior.

Deprecate split-by command (#14019)
# Description
I'm not quite sure what the point of the `split-by` command is. The only
example for the command seems to suggest it's an additional grouping
command. I.e., a record that seems to be the output of the `group-by`
command is passed to `split-by` which then adds an additional layer of
grouping based on a different column.

# User-Facing Changes
Breaking change, deprecated the command.

Always load default env/config values (#14249)
# Release-Notes Short Description

* Nushell now always loads its internal `default_env.nu` before the user
`env.nu` is loaded, then loads the internal `default_config.nu` before
the user's `config.nu` is loaded. This allows for a simpler
user-configuration experience. The Configuration Chapter of the Book
will be updated soon with the new behavior.

# Description

Implements the main ideas in #13671 and a few more:

* Users can now specify only the environment and config options they
want to override in *their* `env.nu` and `config.nu`and yet still have
access to all of the defaults:
* `default_env.nu` (internally defined) will be loaded whenever (and
before) the user's `env.nu` is loaded.
* `default_config.nu` (internally defined) will be loaded whenever (and
before) the user's `config.nu` is loaded.
* No more 900+ line config out-of-the-box.
* Faster startup (again): ~40-45% improvement in launch time with a
default configuration.
* New keys that are added to the defaults in the future will
automatically be available to all users after updating Nushell. No need
to regenerate config to get the new defaults.
* It is now possible to have different internal defaults (which will be
used with `-c` and scripts) vs. REPL defaults. This would have solved
many of the user complaints about the [`display_errors`
implementation](https://www.nushell.sh/blog/2024-09-17-nushell_0_98_0.html#non-zero-exit-codes-are-now-errors-toc).
* A basic "scaffold" `config.nu` and `env.nu` are created on first
launch (if the config directory isn't present).
* Improved "out-of-the-box" experience (OOBE) - No longer asks to create
the files; the minimal scaffolding will be automatically created. If
deleted, they will not be regenerated. This provides a better
"out-of-the-box" experience for the user as they no longer have to make
this decision (without much info on the pros or cons) when first
launching.
* <s>(New: 2024-11-07) Runs the env_conversions process after the
`default_env.nu` is loaded so that users can treat `Path`/`PATH` as
lists in their own config.</s>
* (New: 2024-11-08) Given the changes in #13802, `default_config.nu`
will be a minimal file to minimize load-times. This shaves another (on
my system) ~3ms off the base launch time.
* Related: Keybindings, menus, and hooks that are already internal
defaults are no longer duplicated in `$env.config`. The documentation
will be updated to cover these scenarios.
* (New: 2024-11-08) Move existing "full" `default_config.nu` to
`sample_config.nu` for short-term "documentation" purposes.
* (New: 2024-11-18) Move the `dark-theme` and `light-theme` to Standard
Library and demonstrate their use - Also improves startup times, but
we're reaching the limit of optimization.
* (New: 2024-11-18) Extensively documented/commented `sample_env.nu` and
`sample_config.nu`. These can be displayed in-shell using (for example)
`config nu --sample | nu-highlight | less -R`. Note: Much of this will
eventually be moved to or (some) duplicated in the Doc. But for now,
this some nice in-shell doc that replaces the older
"commented/documented default".
* (New: 2024-11-20) Runs the `ENV_CONVERSIONS` process (1) after the
`default_env.nu` (allows `PATH` to be used as a list in user's `env.nu`)
and (2) before `default_config.nu` is loaded (allows user's
`ENV_CONVERSIONS` from their `env.nu` to be used in their `config.nu`).
* <s>(New: 2024-11-20) The default `ENV_CONVERSIONS` is now an empty
record. The internal Rust code handles `PATH` (and variants) conversions
regardless of the `ENV_CONVERSIONS` variable. This shaves a *very* small
amount of time off the startup.</s> Reset - Looks like there might be a
bug in `nu-enginer::env::ensure_path()` on Windows that would need to be
fixed in order for this to work.

# User-Facing Changes

By default, you shouldn't see much, if any, change when running this
with your existing configuration.

To see the greatest benefit from these changes, you'll probably want to
start with a "fresh" config. This can be easily tested using something
like:

```nushell
let temp_home = (mktemp -d)
$env.XDG_CONFIG_HOME = $temp_home
$env.XDG_DATA_HOME = $temp_home
./target/release/nu
```

You should see a message where the (mostly empty) `env.nu` and
`config.nu` are created on first start. Defaults should be the same (or
similar to) those before the PR. Please let me know if you notice any
differences.

---

Users should now specify configuration in terms of overrides of each
setting. For instance, rather than modifying `history` settings in the
monolithic `config.nu`, the following is recommended in an updated
`config.nu`:

```nu
$env.config.history = {
  file_format: sqlite,
  sync_on_enter: true
  isolation: true
  max_size: 1_000_000
}
```

or even just:

```nu
$env.config.history.file_format = sqlite
$env.config.history.isolation: true
$env.config.history.max_size = 1_000_000
```

Note: It seems many users are already appending a `source my_config.nu`
(or similar pattern) to the end of the existing `config.nu` to make
updates easier. In this case, they will likely want to remove all of the
previous defaults and just move their `my_config.nu` to `config.nu`.

Note: It should be unlikely that there are any breaking changes here,
but there's a slim chance that some code, somewhere, *expects* an
absence of certain config values. Otherwise, all config values are
available before and after this change.

What it says on the tin, this change adds the `mac` and `ip` columns to
the `sys net` command, where `mac` is the interface mac address and `ip`
is a record containing ipv4 and ipv6 addresses as well as whether or not
the address is loopback and multicast. I thought it might be useful to
have this information available in Nushell. This change basically just
pulls extra information out of the underlying structs in the
`sysinfo::Networks` struct. Here's a screenshot from my system:

Rely on display_output hook for formatting values from evaluations (#14361)
# Description

I was reading through the documentation yesterday, when I stumbled upon
[this
section](https://www.nushell.sh/book/pipelines.html#behind-the-scenes)
explaining how command output is formatted using the `table` command. I
was surprised that this section didn't mention the `display_output`
hook, so I took a look in the code and was shocked to discovered that
the documentation was correct, and the `table` command _is_
automatically applied to printed pipelines.

This auto-tabling has two ramifications for the `display_output` hook:

1. The `table` command is called on the output of a pipeline after the
`display_output` has run, even if `display_output` contains the table
command. This means each pipeline output is roughly equivalent to the
following (using `ls` as an example):
    ```nushell
    ls | do $config.hooks.display_output | table
    ```
2. If `display_output` returns structured data, it will _still_ be
formatted through the table command.

This PR removes the auto-table when the `display_output` hook is set.
The auto-table made sense before `display_output` was introduced, but to
me, it now seems like unnecessary "automagic" which can be accomplished
using existing Nushell features.

This means that you can now pull back the curtain a bit, and replace
your `display_output` hook with an empty closure
(`$env.config.hooks.display_output = {||}`, setting it to null retains
the previous behavior) to see the values printed normally without the
table formatting. I think this is a good thing, and makes it easier to
understand Nushell fundamentals.

It is important to note that this PR does not change how `print` and
other commands (well, specifically only `watch`) print out values. They
continue to use `table` with no arguments, so changing your
config/`display_output` hook won't affect what `print`ing a value does.

Rel: [Discord
discussion](https://discord.com/channels/601130461678272522/615329862395101194/1307102690848931904)
(cc @dcarosone)

# User-Facing Changes

Pipelines are no longer automatically formatted using the `table`
command. Instead, the `display_output` hook is used to format pipeline
output. Most users should see no impact, as the default `display_output`
hook already uses the `table` command.
