group-by now returns a table instead of a record (#10848)
# Description

Previously `group-by` returned a record containing each group as a
column. This data layout is hard to work with for some tasks because you
have to further manipulate the result to do things like determine the
number of items in each group, or the number of groups. `transpose` will
turn the record returned by `group-by` into a table, but this is
expensive when `group-by` is run on a large input.

In a discussion with @fdncred [several
workarounds](https://github.com/nushell/nushell/discussions/10462) to
common tasks were discussed, but they seem unsatisfying in general.

Now when `group-by --to-table` is used a table is returned with the
columns "groups" and "items" making it easier to do things like count
the number of groups (`| length`) or count the number of items in each
group (`| each {|g| $g.items | length`)

# User-Facing Changes

* `group-by` returns a `table` with "group" and "items" columns instead
of a `record` with one column per group name

# Tests + Formatting

Tests for `group-by` were updated

# After Submitting

* No breaking changes were made. The new `--to-table` switch should be
added automatically to the [`group-by`
documentation](https://www.nushell.sh/commands/docs/group-by.html)

stdlib: Reduce test file parsing overhead (#10545)
# Description
Retrieving tests and their annotation no longer uses nu --ide-ast
spawned in a subprocess which should reduce test runner startup time.

fix the pretty printing of failing tests in std (#10373)

https://github.com/nushell/nushell/pull/10293/files#diff-371ea1a6b13ef0f2f10ddd0b23b86c54eb8221892e45c2e4c1913a233c585ae7R137

# Description
looks to me like https://github.com/nushell/nushell/pull/10293
introduced the use of `map` command in `std testing`, but it's not a
valid Nushell command, right?

this PR uses `each` as a replacement, that's what the error even says

Remove python-like string multiplication (#10293)
# Description
Currently we support "multiplication" of strings, resulting in a terse
way to repeat a particular string.
This can have unintended side effects when dealing with mixed data (e.g.
after parsing data that is not all numbers).
Furthermore as we frequently fall-back to strings while parsing source
code, this introduced a runaway edge case in const evaluation (#10212)

Work for #10233

## Details
- Remove python-like string multiplication.
- Workaround for indentation
  - This should probably be addressed with a purpose built command
- Remove special const-eval error test

# User-Facing Changes
**Major breaking change!**
`"string" * 42` will stop working. (This was used for example in the
stdlib)

We should bless a good alternative before landing this

Test-runner performance improved by:
* Not loading user config or stdlib during ide parsing
* Not loading user config during test execution
* Running tests in parallel instead of serially
On my machine `toolkit test stdlib` execution time went from 38s to 15s
(with all code precompiled)

Use regex match for test include/exclude and module exclude to allow for
multiple tests/modules to be excluded.

test-runner: Add option to exclude single test and module (#9611)
# Description
This PR adds two additional flags to the test runner `--exclude` and
`--exclude-module` which as the name suggests allow to exclude tests
from a run
The now options only support a single test / module to exclude.

# Description
Test runner now uses annotations instead of magic function names to pick
up code to run. Additionally skipping tests is now done on annotation
level so skipping and unskipping a test no longer requires changes to
the test code

In order for a function to be picked up by the test runner it needs to
meet following criteria:
* Needs to be private (all exported functions are ignored)
* Needs to contain one of valid annotations (and only the annotation)
directly above the definition, all other comments are ignored

Following are considered valid annotations:
* \# test
* \# test-skip
* \# before-all
* \# before-each
* \# after-each
* \# after-all

std: refactor test-runner to no longer require tests to be exported (#9355)
# Description
Test runner now performs following actions in order to run tests:
* Module file is opened
* Public function with random name is added to the source code, this
function calls user-specified private function
* Modified module file is saved under random name in $nu.temp-path
* Modified module file is imported in subprocess, injected function is
called by the test runner
# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
* Test functions no longer need to be exported
* test functions no longer need to reside in separate test_ files
* setup and teardown renamed to before-each and after-each respectively
* before-all and after-all functions added that run before all tests in
given module. This matches the behavior of test runners used by other
languages such as JUnit/TestNG or Mocha

REFACTOR: move run-tests and fix the std assert namespace (#9303)
related to the namespace bullet point in
- https://github.com/nushell/nushell/issues/8450

# Description
this was the last module of the standard library with a broken
namespace, this PR takes care of this.

- `run-tests` has been moved to `std/mod.nu`
- `std/testing.nu` has been moved to `std/assert.nu`
- the namespace has been fixed
- `assert` is now called `main` and used in all the other `std assert`
commands
- for `std assert length` and `std assert str contains`, in order not to
shadow the built-in `length` and `str contains` commands, i've used
`alias "core ..." = ...` to (1) define `foo` in `assert.nu` and (2)
still use the builtin `foo` with `core foo` (replace `foo` by `length`
or `str contains`)
  - tests have been fixed accordingly

# User-Facing Changes
one can not use
```
use std "assert equal"
```
anymore because `assert ...` is not exported from `std`.
`std assert` is now a *real* module.

# Tests + Formatting
- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
-  `toolkit test`
-  `toolkit test stdlib`

# After Submitting
```
$nothing
```

# Notes for reviewers
to test this, i think the easiest is to
- run `toolkit test stdlib` and see all the tests pass
- run `cargo run -- -n` and try `use std assert` => are all the commands
available in scope?
