MsgPack deserializer: improve handling of EOF (#12183)
# Description

`rmp_serde` has two kinds of errors that contain I/O errors, and an EOF
can occur inside either of them, but we were only treating an EOF inside
an `InvalidMarkerRead` as an EOF, which would make sense for the
beginning of a message.

However, we should also treat an incomplete message + EOF as an EOF.
There isn't really any point in reporting that an EOF was received
mid-message.

This should fix the issue where the
`seq_describe_no_collect_succeeds_without_error` test would sometimes
fail, as doing a `describe --no-collect` followed by nushell exiting
could (but was not guaranteed to) cause this exact scenario.

# User-Facing Changes
Will probably remove useless `read error` messages from plugins after
exit of `nu`

More robustness improvements to plugin persistence tests (#12185)
# Description

These tests have been causing some pain, so I've done a few more things
to try to make them a bit more tolerant of running slowly.

- `plugin_process_exits_after_stop`: using timeout strategy, allows the
process 5 seconds to exit.

- generally don't use sleep to test anything less than 100ms

Because `std::fs::canonicalize` requires the path to exist, this PR
makes it so that when canonicalizing any config file, the
`$nu.default-config-dir/nushell` part is canonicalized first, then
`$nu.default-config-dir/nushell/foo.nu` is canonicalized.

This should also fix the issue @devyn pointed out
[here](https://github.com/nushell/nushell/pull/12118#issuecomment-1989546708)
where a couple of the tests failed if one's `~/.config/nushell` folder
was actually a symlink to a different folder. The tests previously
didn't canonicalize the expected paths.

I was going to make a PR that caches the config directory on startup (as
suggested by fdncred and Ian in Discord), but I can make that part of
this PR if we want to avoid creating unnecessary PRs. I think it
probably makes more sense to separate them though.

Bump rayon from 1.8.1 to 1.9.0 (#12186)

<blockquote>
<h1>Release rayon 1.9.0 (2024-02-27)</h1>
<ul>
<li>The new methods
<code>IndexedParallelIterator::by_exponential_blocks</code> and
<code>by_uniform_blocks</code> allow processing items in smaller groups
at a time.</li>
<li>The new <code>iter::walk_tree</code>, <code>walk_tree_prefix</code>,
and <code>walk_tree_postfix</code>
functions enable custom parallel iteration over tree-like
structures.</li>
<li>The new method <code>ParallelIterator::collect_vec_list</code>
returns items as a linked
list of vectors, which is an efficient mode of parallel collection used
by
many of the internal implementations of <code>collect</code>.</li>
<li>The new methods
<code>ParallelSliceMut::par_split_inclusive_mut</code>,
<code>ParallelSlice::par_split_inclusive</code>, and
<code>ParallelString::par_split_inclusive</code> all work like a normal
split but
keeping the separator as part of the left slice.</li>
<li>The new <code>ParallelString::par_split_ascii_whitespace</code>
splits only on ASCII
whitespace, which is faster than including Unicode multi-byte
whitespace.</li>
<li><code>OsString</code> now implements
<code>FromParallelIterator&lt;_&gt;</code> and
<code>ParallelExtend&lt;_&gt;</code>
for a few item types similar to the standard <code>FromIterator</code>
and <code>Extend</code>.</li>
<li>The internal <code>Pattern</code> trait for string methods is now
implemented for
<code>[char; N]</code> and <code>&amp;[char; N]</code>, matching any of
the given characters.</li>

Fix locking soundness in PersistentPlugin (#12182)
# Description

There were two problems in `PersistentPlugin` which could cause a
deadlock:

1. There were two mutexes being used, and `get()` could potentially hold
both simultaneously if it had to spawn. This won't necessarily cause a
deadlock on its own, but it does mean that lock order is sensitive

2. `set_gc_config()` called `flush()` while still holding the lock,
meaning that the GC thread had to proceed before the lock was released.
However, waiting for the GC thread to proceed could mean waiting for the
GC thread to call `stop()`, which itself would try to lock the mutex.
So, it's not safe to wait for the GC thread while the lock is held. This
is fixed now.

I've also reverted #12177, as @IanManske reported that this was also
happening for him on Linux, and it seems to be this problem which should
not be platform-specific at all. I believe this solves it.

Disable plugin GC tests on macOS (#12177)
# Description
These are hanging the CI sometimes, and that's no good. I'll try to
figure out how to make these tests pass consistently in the meantime.

work on macOS, so hopefully it's not a big problem, but we won't know
until I'm able to track down the problem.

Add environment engine calls for plugins (#12166)
# Description

This adds three engine calls: `GetEnvVar`, `GetEnvVars`, for getting
environment variables from the plugin command context, and
`GetCurrentDir` for getting the current working directory.

Plugins are now launched in the directory of their executable to try to
make improper use of the current directory without first setting it more
obvious. Plugins previously launched in whatever the current directory
of the engine was at the time the plugin command was run, but switching
to persistent plugins broke this, because they stay in whatever
directory they launched in initially.

This also fixes the `gstat` plugin to use `get_current_dir()` to
determine its repo location, which was directly affected by this
problem.

# User-Facing Changes
- Adds new engine calls (`GetEnvVar`, `GetEnvVars`, `GetCurrentDir`)
- Runs plugins in a different directory from before, in order to catch
bugs
- Plugins will have to use the new engine calls if they do filesystem
stuff to work properly

# Tests + Formatting

- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting

Sync with the plugin garbage collector when setting config (#12152)
# Description
This causes `PersistentPlugin` to wait for the plugin garbage collector
to actually receive and process its config when setting it in
`set_gc_config`.

The motivation behind doing this is to make setting GC config in scripts
more deterministic. Before this change we couldn't really guarantee that
the GC could see your config before you started doing other things.

There is a slight cost to performance to doing this - we set config
before each plugin call because we don't necessarily know that it
reflects what's in `$env.config`, and now to do that we have to
synchronize with the GC thread.

This was probably the cause of spuriously failing tests as mentioned by
@sholderbach. Hopefully this fixes it. It might be the case that
launching threads on some platforms (or just on a really busy test
runner) sometimes takes a significant amount of time.

# User-Facing Changes
- possibly slightly worse performance for plugin calls

Support for all custom value operations on plugin custom values (#12088)
# Description

Adds support for the following operations on plugin custom values, in
addition to `to_base_value` which was already present:

- `follow_path_int()`
- `follow_path_string()`
- `partial_cmp()`
- `operation()`
- `Drop` (notification, if opted into with
`CustomValue::notify_plugin_on_drop`)

There are additionally customizable methods within the `Plugin` and
`StreamingPlugin` traits for implementing these functions in a way that
requires access to the plugin state, as a registered handle model such
as might be used in a dataframes plugin would.

`Value::append` was also changed to handle custom values correctly.

# User-Facing Changes

- Signature of `CustomValue::follow_path_string` and
`CustomValue::follow_path_int` changed to give access to the span of the
custom value itself, useful for some errors.
- Plugins using custom values have to be recompiled because the engine
will try to do custom value operations that aren't supported
- Plugins can do more things 🎉 

# Tests + Formatting
Tests were added for all of the new custom values functionality.

- 🟢 `toolkit fmt`
- 🟢 `toolkit clippy`
- 🟢 `toolkit test`
- 🟢 `toolkit test stdlib`

# After Submitting
- [ ] Document protocol reference `CustomValueOp` variants:
  - [ ] `FollowPathInt`
  - [ ] `FollowPathString`
  - [ ] `PartialCmp`
  - [ ] `Operation`
  - [ ] `Dropped`
- [ ] Document `notify_on_drop` optional field in `PluginCustomValue`

As described in #12103, this PR makes Nushell use `XDG_CONFIG_HOME` as
the config directory if it exists. Otherwise, it uses the old behavior,
which was to use `dirs_next::config_dir()`.

Edit: We discussed choosing between `XDG_CONFIG_HOME` and the default
config directory in Discord and decided against it, at least for now.

<s>@kubouch also suggested letting users choose between
`XDG_CONFIG_HOME` and the default config directory if config files
aren't found on startup and `XDG_CONFIG_HOME` is set to a value
different from the default config directory</s>

On Windows and MacOS, if the `XDG_CONFIG_HOME` variable is set but
`XDG_CONFIG_HOME` is either empty or doesn't exist *and* the old config
directory is non-empty, Nushell will issue a warning on startup saying
that it won't move files from the old config directory to the new one.
To do this, I had to add a `nu_path::config_dir_old()` function. I
assume that at some point, we will remove the warning message and the
function can be removed too. Alternatively, instead of having that
function there, `main.rs` could directly call `dirs_next::config_dir()`.

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

When `$env.XDG_CONFIG_HOME` is set to an absolute path, Nushell will use
`$"($env.XDG_CONFIG_HOME)/nushell"` as its config directory (previously,
this only worked on Linux).

To use `App Data\Roaming` (Windows) or `Library/Application Support`
(MacOS) instead (the old behavior), one can either leave
`XDG_CONFIG_HOME` unset or set it to an empty string.

If `XDG_CONFIG_HOME` is set, but to a non-absolute/invalid path, Nushell
will report an error on startup and use the default config directory
instead:

`~/.config`, so the documentation could warn about that mistake.

Make the plugin persistence GC delay test more reliable (#12153)
# Description

This makes the test a bit more complicated, but implements a timeout
loop in the script. As long as the test completes in 5 seconds it's
considered to be ok. The default is 10 seconds, so that would still be
half that.

This should help with running on the busy CI where things sometimes take
a while. Unfortunately this is a timing sensitive test. The alternative
is basically to just not test this at all because it's too difficult to
guarantee that it will complete in time. If we continue to have issues,
I might just have to take that route instead.

do command: Make closure support default parameters and type checking (#12056)
# Description
Fixes: #11287
Fixes: #11318

It's implemented by porting the similar logic in `eval_call`, I've tried
to reduce duplicate code, but it seems that it's hard without using
macros.

3ee2fc60f9/crates/nu-engine/src/eval.rs (L60-L130)

It only works for `do` command.

# User-Facing Changes
## Closure supports optional parameter
```nushell
let code = {|x?| print ($x | default "i'm the default")}
do $code
```
Previously it raises an error, after this change, it prints `i'm the
default`.

## Closure supports type checking
```nushell
let code = {|x: int| echo $x}
do $code "aa"
```
After this change, it will raise an error with a message: `can't convert
string to int`

Restructure nu-protocol in more meaningful units (#11917)
This is partially "feng-shui programming" of moving things to new
separate places.

The later commits include "`git blame` tollbooths" by moving out chunks
of code into new files, which requires an extra step to track things
with `git blame`. We can negiotiate if you want to keep particular
things in their original place.

If egregious I tried to add a bit of documentation. If I see something
that is unused/unnecessarily `pub` I will try to remove that.


- Move `nu_protocol::Exportable` to `nu-parser`
- Guess doccomment for `Exportable`
- Move `Unit` enum from `value` to `AST`
- Move engine state `Variable` def into its folder
- Move error-related files in `nu-protocol` subdir
- Move `pipeline_data` module into its own folder
- Move `stream.rs` over into the `pipeline_data` mod
- Move `PipelineMetadata` into its own file
- Doccomment `PipelineMetadata`
- Remove unused `is_leap_year` in `value/mod`
- Note about criminal `type_compatible` helper
- Move duration fmting into new `value/duration.rs`
- Move filesize fmting logic to new `value/filesize`
- Split reexports from standard imports in `value/mod`

Remove feat extra and include in default (#12140)
# Description
The intended effect of the `extra` feature has been undermined by
introducing the full builds on our release pages and having more
activity on some of the extra commands.

To simplify the feature matrix let's get rid of it and focus our effort
on truly either refining a command to well-specified behavior or
discarding it entirely from the `nu` binary and moving it into plugins.

## Details
- Remove `--features extra` from CI
- Don't explicitly name `extra` in full build wf
- Remove feature extra from build-help scripts
- Update README in `nu-cmd-extra`
- Remove feature `extra`
- Fix previously dead `format pattern` tests
- Relax signature of `to html`
- Fix/ignore `html::test_no_color_flag`
- Remove dead features from `version`
- Refine `to html` type signature

# User-Facing Changes
The commands that were previously only available when building with
`--features extra` will now be available to everyone. This increases the
number of dependencies slightly but has a limited impact on the overall
binary size.

# Tests + Formatting
Some tests that were left in `nu-command` during cratification were dead
because the feature was not passed to `nu-command` and only to
`nu-cmd-lang` for feature-flag mention in `version`.
Those tests have now been either fixed or ignored in one case.

# After Submitting
There may be places in the documentation where we point to `--features
extra` that will now be moot (apart from the generated command help)

Canonicalize config dir (#12136)
It turns out that my previous PR,
https://github.com/nushell/nushell/pull/11999, didn't properly
canonicalize `$nu.default-config-dir` in a scenario where
`XDG_CONFIG_HOME` (or the equivalent on each platform) was a symlink. To
remedy that, this PR makes `nu_path::config_dir()` return a
canonicalized path. This probably shouldn't break anything (except maybe
tests relying on the old behavior), since the canonical path will be
equivalent to non-canonical paths.

# User-Facing Changes

A user may get a path with symlinks resolved and `..`s replaced where
they previously didn't. I'm not sure where this would happen, though,
and anyway, the canonical path is probably the "correct" thing to
present to the user. We're using `omnipath` to make the path presentable
to the user on Windows, so there's no danger of someone getting an path
with `\\?` there.

# Tests + Formatting

The tests for config files have been updated to run the binary using the
`Director` so that it has access to the `XDG_CONFIG_HOME`/`HOME`
environment variables to be able to change the config directory.

Keep plugins persistently running in the background (#12064)
# Description
This PR uses the new plugin protocol to intelligently keep plugin
processes running in the background for further plugin calls.

Running plugins can be seen by running the new `plugin list` command,
and stopped by running the new `plugin stop` command.

This is an enhancement for the performance of plugins, as starting new
plugin processes has overhead, especially for plugins in languages that
take a significant amount of time on startup. It also enables plugins
that have persistent state between commands, making the migration of
features like dataframes and `stor` to plugins possible.

Plugins are automatically stopped by the new plugin garbage collector,
configurable with `$env.config.plugin_gc`:

```nushell
  $env.config.plugin_gc = {
      # Configuration for plugin garbage collection
      default: {
          enabled: true # true to enable stopping of inactive plugins
          stop_after: 10sec # how long to wait after a plugin is inactive to stop it
      }
      plugins: {
          # alternate configuration for specific plugins, by name, for example:
          #
          # gstat: {
          #     enabled: false
          # }
      }
  }
```

If garbage collection is enabled, plugins will be stopped after
`stop_after` passes after they were last active. Plugins are counted as
inactive if they have no running plugin calls. Reading the stream from
the response of a plugin call is still considered to be activity, but if
a plugin holds on to a stream but the call ends without an active
streaming response, it is not counted as active even if it is reading
it. Plugins can explicitly disable the GC as appropriate with
`engine.set_gc_disabled(true)`.

The `version` command now lists plugin names rather than plugin
commands. The list of plugin commands is accessible via `plugin list`.

Recommend doing this together with #12029, because it will likely force
plugin developers to do the right thing with mutability and lead to less
unexpected behavior when running plugins nested / in parallel.

# User-Facing Changes
- new command: `plugin list`
- new command: `plugin stop`
- changed command: `version` (now lists plugin names, rather than
commands)
- new config: `$env.config.plugin_gc`
- Plugins will keep running and be reused, at least for the configured
GC period
- Plugins that used mutable state in weird ways like `inc` did might
misbehave until fixed
- Plugins can disable GC if they need to
- Had to change plugin signature to accept `&EngineInterface` so that
the GC disable feature works. #12029 does this anyway, and I'm expecting
(resolvable) conflicts with that

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

Because there is some specific OS behavior required for plugins to not
respond to Ctrl-C directly, I've developed against and tested on both
Linux and Windows to ensure that works properly.

I think this probably needs to be in the book somewhere

Add support for engine calls from plugins (#12029)
# Description

This allows plugins to make calls back to the engine to get config,
evaluate closures, and do other things that must be done within the
engine process.

Engine calls can both produce and consume streams as necessary. Closures
passed to plugins can both accept stream input and produce stream output
sent back to the plugin.

Engine calls referring to a plugin call's context can be processed as
long either the response hasn't been received, or the response created
streams that haven't ended yet.

This is a breaking API change for plugins. There are some pretty major
changes to the interface that plugins must implement, including:

1. Plugins now run with `&self` and must be `Sync`. Executing multiple
plugin calls in parallel is supported, and there's a chance that a
closure passed to a plugin could invoke the same plugin. Supporting
state across plugin invocations is left up to the plugin author to do in
whichever way they feel best, but the plugin object itself is still
shared. Even though the engine doesn't run multiple plugin calls through
the same process yet, I still considered it important to break the API
in this way at this stage. We might want to consider an optional
threadpool feature for performance.

2. Plugins take a reference to `EngineInterface`, which can be cloned.
This interface allows plugins to make calls back to the engine,
including for getting config and running closures.

3. Plugins no longer take the `config` parameter. This can be accessed
from the interface via the `.get_plugin_config()` engine call.


# User-Facing Changes
<!-- List of all changes that impact the user experience here. This
helps us keep track of breaking changes. -->
Not only does this have plugin protocol changes, it will require plugins
to make some code changes before they will work again. But on the plus
side, the engine call feature is extensible, and we can add more things
to it as needed.

Plugin maintainers will have to change the trait signature at the very
least. If they were using `config`, they will have to call
`engine.get_plugin_config()` instead.

If they were using the mutable reference to the plugin, they will have
to come up with some strategy to work around it (for example, for `Inc`
I just cloned it). This shouldn't be such a big deal at the moment as
it's not like plugins have ever run as daemons with persistent state in
the past, and they don't in this PR either. But I thought it was
important to make the change before we support plugins as daemons, as an
exclusive mutable reference is not compatible with parallel plugin
calls.

I suggest this gets merged sometime *after* the current pending release,
so that we have some time to adjust to the previous plugin protocol
changes that don't require code changes before making ones that do.

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


# After Submitting
I will document the additional protocol features (`EngineCall`,
`EngineCallResponse`), and constraints on plugin call processing if
engine calls are used - basically, to be aware that an engine call could
result in a nested plugin call, so the plugin should be able to handle
that.

This PR refactors `nu-check` and makes it possible to check module
directories. Also removes the requirement for files to end with .nu: It
was too limiting for module directories and there are executable scripts
[around](https://github.com/nushell/nu_scripts/tree/main/make_release/release-note)
that do not end with .nu, it's a common practice for scripts to omit it.

Other changes are:
* Removed the `--all` flag and heuristic parse because these are
irrelevant now when module syntax is a subset of script syntax (i.e.,
every module can be parsed as script).
* Reduced code duplication and in general tidied up the code
* Replaced unspanned errors with spanned ones.

Allow for stacks to have parents (#11654)
This is another attempt on #11288 

This allows for a `Stack` to have a parent stack (behind an `Arc`). This
is being added to avoid constant stack copying in REPL code.

Concretely the following changes are included here:
- `Stack` can now have a `parent_stack`, pointing to another stack
- variable lookups can fallback to this parent stack (env vars and
everything else is still copied)
- REPL code has been reworked so that we use parenting rather than
cloning. A REPL-code-specific trait helps to ensure that we do not
accidentally trigger a full clone of the main stack
- A property test has been added to make sure that parenting "looks the
same" as cloning for consumers of `Stack` objects

It looks like `Playground` and `Director` in nu-tests-support haven't
gotten much love recently, so this PR is for updating them to work with
newer Nushell versions.

- `Director` adds a `--skip-plugins` argument before running `nu`, but
that doesn't exist anymore, so I removed it.
- `Director` also adds a `--perf` argument, which also doesn't exist
anymore. I added `--log-level info` instead to get the performance
output.
- It doesn't seem like anyone was using `playground::matchers`, and it
used the [hamcrest2](https://github.com/Valloric/hamcrest2-rust) crate,
which appears to be unmaintained, so I got rid of that (and the
`hamcrest2` dependency).
- Inside `tests/fixtures/playground/config` were two files in the old
config format: `default.toml` and `startup.toml`. I removed those too.

Fix up ctrl+C handling in into_sqlite (#12130)
I noticed that ctrl+C handling wasn't fully wired up in `into sqlite`,
for some data types we were ignoring ctrl+C presses.

I fixed that up and also made sure we roll back the current transaction
when cancelling (without that, I think we leak memory and database
locks).

This PR adds a new evaluator path with callbacks to a mutable trait
object implementing a Debugger trait. The trait object can do anything,
e.g., profiling, code coverage, step debugging. Currently,
entering/leaving a block and a pipeline element is marked with
callbacks, but more callbacks can be added as necessary. Not all
callbacks need to be used by all debuggers; unused ones are simply empty
calls. A simple profiler is implemented as a proof of concept.

The debugging support is implementing by making `eval_xxx()` functions
generic depending on whether we're debugging or not. This has zero
computational overhead, but makes the binary slightly larger (see
benchmarks below). `eval_xxx()` variants called from commands (like
`eval_block_with_early_return()` in `each`) are chosen with a dynamic
dispatch for two reasons: to not grow the binary size due to duplicating
the code of many commands, and for the fact that it isn't possible
because it would make Command trait objects object-unsafe.

In the future, I hope it will be possible to allow plugin callbacks such
that users would be able to implement their profiler plugins instead of
having to recompile Nushell.
[DAP](https://microsoft.github.io/debug-adapter-protocol/) would also be
interesting to explore.

Try `help debug profile`.

## Screenshots

Basic output:

![profiler_new](https://github.com/nushell/nushell/assets/25571562/418b9df0-b659-4dcb-b023-2d5fcef2c865)

To profile with more granularity, increase the profiler depth (you'll
see that repeated `is-windows` calls take a large chunk of total time,
making it a good candidate for optimizing):

![profiler_new_m3](https://github.com/nushell/nushell/assets/25571562/636d756d-5d56-460c-a372-14716f65f37f)

## Benchmarks

### Binary size

Binary size increase vs. main: **+40360 bytes**. _(Both built with
`--release --features=extra,dataframe`.)_

### Time

```nushell
# bench_debug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'debug:'
let res2 = bench { debug profile $test } --pretty
print $res2
```

```nushell
# bench_nodebug.nu
use std bench

let test = {
    1..100
    | each {
        ls | each {|row| $row.name | str length }
    }
    | flatten
    | math avg
}

print 'no debug:'
let res1 = bench { do $test } --pretty
print $res1
```

`cargo run --release -- bench_debug.nu` is consistently 1--2 ms slower
than `cargo run --release -- bench_nodebug.nu` due to the collection
overhead + gathering the report. This is expected. When gathering more
stuff, the overhead is obviously higher.

`cargo run --release -- bench_nodebug.nu` vs. `nu bench_nodebug.nu` I
didn't measure any difference. Both benchmarks report times between 97
and 103 ms randomly, without one being consistently higher than the
other. This suggests that at least in this particular case, when not
running any debugger, there is no runtime overhead.

## API changes

This PR adds a generic parameter to all `eval_xxx` functions that forces
you to specify whether you use the debugger. You can resolve it in two
ways:
* Use a provided helper that will figure it out for you. If you wanted
to use `eval_block(&engine_state, ...)`, call `let eval_block =
get_eval_block(&engine_state); eval_block(&engine_state, ...)`
* If you know you're in an evaluation path that doesn't need debugger
support, call `eval_block::<WithoutDebug>(&engine_state, ...)` (this is
the case of hooks, for example).

I tried to add more explanation in the docstring of `debugger_trait.rs`.

## TODO

- [x] Better profiler output to reduce spam of iterative commands like
`each`
- [x] Resolve `TODO: DEBUG` comments
- [x] Resolve unwraps
- [x] Add doc comments
- [x] Add usage and extra usage for `debug profile`, explaining all
columns

Hopefully none.

# Tests + Formatting
<!--
Don't forget to add tests that cover your changes.

Make sure you've run and fixed any issues with these commands:

- `cargo fmt --all -- --check` to check standard code formatting (`cargo
fmt --all` applies these changes)
- `cargo clippy --workspace -- -D warnings -D clippy::unwrap_used` to
check that you're using the standard code style
- `cargo test --workspace` to check that all tests pass (on Windows make
sure to [enable developer
mode](https://learn.microsoft.com/en-us/windows/apps/get-started/developer-mode-features-and-debugging))
- `cargo run -- -c "use std testing; testing run-tests --path
crates/nu-std"` to run the tests for the standard library

> **Note**
> from `nushell` you can also use the `toolkit` as follows
> ```bash
> use toolkit.nu # or use an `env_change` hook to activate it
automatically
> toolkit check pr

Improve the error message for a plugin version mismatch (#12122)
# Description

Previously, the plugin itself would also print error messages about
mismatched versions, and there could be many of them while parsing a
`register` command which would be hard to follow. This removes that
behavior so that the error message is easier to read, and also makes the
error message on the engine side mention the plugin name so that it's
easier to tell which plugin needs to be updated.

The python plugin has also been modified to make testing this behavior
easier. Just change `NUSHELL_VERSION` in the script file to something
incompatible.

Change the ignore command to use drain() instead of collecting a value (#12120)
# Description

Change the `ignore` command to use `drain()` instead of collecting a
value.

This saves memory usage when piping a lot of output to `ignore`. There's
no reason to keep the output in memory if it's going to be discarded
anyway.

Introduce workspace dependencies (#12043)
# Description
This PR introduces [workspaces
dependencies](https://doc.rust-lang.org/cargo/reference/workspaces.html#the-dependencies-table).
The advantages are:
- a single place where dependency versions are declared
- reduces the number of files to change when upgrading a dependency
- reduces the risk of accidentally depending on 2 different versions of
the same dependency

I've only done a few so far. If this PR is accepted, I might continue
and progressively do the rest.
