Make ast::Call::span() and arguments_span() more robust (#13412)
# Description

Trying to help @amtoine out here - the spans calculated by `ast::Call`
by `span()` and `argument_span()` are suspicious and are not properly
guarding against `end` that might be before `start`. Just using
`Span::merge()` / `merge_many()` instead to try to make the behaviour as
simple and consistent as possible. Hopefully then even if the arguments
have some crazy spans, we don't have spans that are just totally
invalid.

Use directories for autoloading (#13382)
fixes https://github.com/nushell/nushell/issues/13378

# Description

This PR tries to improve usage of system APIs to determine the location
of vendored autoload files.

# User-Facing Changes
The paths listed in #13180 and #13217 are changing. This has not been
part of a release yet, so arguably the user facing changes are only to
unreleased features anyway.

# Tests + Formatting
Haven't done, but if someone wants to help me here, I'm open to doing
it. I just don't know how to properly test this.

generate: switch the position of <initial> and <closure>, so the closure can have default parameters (#13393)
# Description
Close: #12083 
Close: #12084 

# User-Facing Changes
It's a breaking change because we have switched the position of
`<initial>` and `<closure>`, after the change, initial value will be
optional. So it's possible to do something like this:

```nushell
> let f = {|fib = [0, 1]| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
> generate $f | first 5
╭───┬───╮
│ 0 │ 0 │
│ 1 │ 1 │
│ 2 │ 1 │
│ 3 │ 2 │
│ 4 │ 3 │
╰───┴───╯
```

It will also raise error if user don't give initial value, and the
closure don't have default parameter.
```nushell
❯ let f = {|fib| {out: $fib.0, next: [$fib.1, ($fib.0 + $fib.1)]} }
❯ generate $f
Error:   × The initial value is missing
   ╭─[entry #5:1:1]
 1 │ generate $f
   · ────┬───
   ·     ╰── Missing intial value
   ╰────
  help: Provide <initial> value in generate, or assigning default value to closure parameter

```

Make plugins able to find and call other commands (#13407)
# Description

Adds functionality to the plugin interface to support calling internal
commands from plugins. For example, using `view ir --json`:

```rust
let closure: Value = call.req(0)?;

let Some(decl_id) = engine.find_decl("view ir")? else {
    return Err(LabeledError::new("`view ir` not found"));
};

let ir_json = engine.call_decl(
    decl_id,
    EvaluatedCall::new(call.head)
        .with_named("json".into_spanned(call.head), Value::bool(true, call.head))
        .with_positional(closure),
    PipelineData::Empty,
    true,
    false,
)?.into_value()?.into_string()?;

let ir = serde_json::from_value(&ir_json);

// ...
```

# User-Facing Changes

Plugin developers can now use `EngineInterface::find_decl()` and
`call_decl()` to call internal commands, which could be handy for
formatters like `to csv` or `to nuon`, or for reflection commands that
help gain insight into the engine.

Refactor window (#13401)
# Description
Following from #13377, this PR refactors the related `window` command.
In the case where `window` should behave exactly like `chunks`, it now
reuses the same code that `chunks` does. Otherwise, the other cases have
been rewritten and have resulted in a performance increase:

| window size | stride | old time (ms) | new time (ms) |
| -----------:| ------:| -------------:| -------------:|
| 20          | 1      | 757           | 722           |
| 2           | 1      | 364           | 333           |
| 1           | 1      | 343           | 293           |
| 20          | 20     | 90            | 63            |
| 2           | 2      | 215           | 175           |
| 20          | 30     | 74            | 60            |
| 2           | 4      | 141           | 110           |


# User-Facing Changes
`window` will now error if the window size or stride is 0, which is
technically a breaking change.

Overhaul $in expressions (#13357)
# Description

This grew quite a bit beyond its original scope, but I've tried to make
`$in` a bit more consistent and easier to work with.

Instead of the parser generating calls to `collect` and creating
closures, this adds `Expr::Collect` which just evaluates in the same
scope and doesn't require any closure.

When `$in` is detected in an expression, it is replaced with a new
variable (also called `$in`) and wrapped in `Expr::Collect`. During
eval, this expression is evaluated directly, with the input and with
that new variable set to the collected value.

Other than being faster and less prone to gotchas, it also makes it
possible to typecheck the output of an expression containing `$in`,
which is nice. This is a breaking change though, because of the lack of
the closure and because now typechecking will actually happen. Also, I
haven't attempted to typecheck the input yet.

The IR generated now just looks like this:

```gas
collect        %in
clone          %tmp, %in
store-variable $in, %tmp
# %out <- ...expression... <- %in
drop-variable  $in
```

(where `$in` is the local variable created for this collection, and not
`IN_VARIABLE_ID`)

which is a lot better than having to create a closure and call `collect
--keep-env`, dealing with all of the capture gathering and allocation
that entails. Ideally we can also detect whether that input is actually
needed, so maybe we don't have to clone, but I haven't tried to do that
yet. Theoretically now that the variable is a unique one every time, it
should be possible to give it a type - I just don't know how to
determine that yet.

On top of that, I've also reworked how `$in` works in pipeline-initial
position. Previously, it was a little bit inconsistent. For example,
this worked:

```nushell
> 3 | do { let x = $in; let y = $in; print $x $y }
3
3
```

However, this causes a runtime variable not found error on the second
`$in`:

```nushell
> def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
Error: nu:🐚:variable_not_found

  × Variable not found
   ╭─[entry #115:1:35]
 1 │ def foo [] { let x = $in; let y = $in; print $x $y }; 3 | foo
   ·                                   ─┬─
   ·                                    ╰── variable not found
   ╰────
```

I've fixed this by making the first element `$in` detection *always*
happen at the block level, so if you use `$in` in pipeline-initial
position anywhere in a block, it will collect with an implicit
subexpression around the whole thing, and you can then use that `$in`
more than once. In doing this I also rewrote `parse_pipeline()` and
hopefully it's a bit more straightforward and possibly more efficient
too now.

Finally, I've tried to make `let` and `mut` a lot more straightforward
with how they handle the rest of the pipeline, and using a redirection
with `let`/`mut` now does what you'd expect if you assume that they
consume the whole pipeline - the redirection is just processed as
normal. These both work now:

```nushell
let x = ^foo err> err.txt
let y = ^foo out+err>| str length
```

It was previously possible to accomplish this with a subexpression, but
it just seemed like a weird gotcha that you couldn't do it. Intuitively,
`let` and `mut` just seem to take the whole line.

- closes #13137

# User-Facing Changes
- `$in` will behave more consistently with blocks and closures, since
the entire block is now just wrapped to handle it if it appears in the
first pipeline element
- `$in` no longer creates a closure, so what can be done within an
expression containing `$in` is less restrictive
- `$in` containing expressions are now type checked, rather than just
resulting in `any`. However, `$in` itself is still `any`, so this isn't
quite perfect yet
- Redirections are now allowed in `let` and `mut` and behave pretty much
how you'd expect

Remove default list-diving behaviour (#13386)
# Description

Before this change `default` would dive into lists and replace `null`
elements with the default value.
Therefore there was no easy way to process `null|list<null|string>`
input and receive `list<null|string>`
(IOW to apply the default on the top level only).

However it's trivially easy to apply default values to list elements
with the `each` command:
```nushell
[null, "a", null] | each { default "b" }
```

So there's no need to have this behavior in `default` command.

# User-Facing Changes

* `default` no longer dives into lists to replace `null` elements with
the default value.

# Tests + Formatting

Added a couple of tests for the new (and old) behavior.

# After Submitting

* Update docs.

Deprecate group in favor of chunks (#13377)
# Description
The name of the `group` command is a little unclear/ambiguous.
Everything I look at it, I think of `group-by`. I think `chunks` more
clearly conveys what the `group` command does. Namely, it divides the
input list into chunks of a certain size. For example,
[`slice::chunks`](https://doc.rust-lang.org/std/primitive.slice.html#method.chunks)
has the same name. So, this PR adds a new `chunks` command to replace
the now deprecated `group` command.

The `chunks` command is a refactored version of `group`. As such, there
is a small performance improvement:
```nushell
# $data is a very large list
> bench { $data | chunks 2 } --rounds 30 | get mean
474ms 921µs 190ns

# deprecation warning was disabled here for fairness
> bench { $data | group 2 } --rounds 30 | get mean
592ms 702µs 440ns



> bench { $data | chunks 200 } --rounds 30 | get mean
374ms 188µs 318ns

> bench { $data | group 200 } --rounds 30 | get mean
481ms 264µs 869ns 



> bench { $data | chunks 1 } --rounds 30 | get mean
642ms 574µs 42ns

> bench { $data | group 1 } --rounds 30 | get mean
981ms 602µs 513ns
```

# User-Facing Changes
- `group` command has been deprecated in favor of new `chunks` command.
- `chunks` errors when given a chunk size of `0` whereas `group` returns
chunks with one element.

# Tests + Formatting
Added tests for `chunks`, since `group` did not have any tests.

# After Submitting
Update book if necessary.

Fix CI test failure on main (nu-json) (#13374)

JSON format output keeps braces on same line (issue #13326) (#13352)
# Description
This is a minor breaking change to JSON output syntax/style of the `to
json` command.

This fixes #13326 by setting `braces_same_line` to true when creating a
new `HjsonFormatter`.
This then simply tells `HjsonFormatter` to keep the braces on the same
line when outputting which is what I expected nu's `to json` command to
do.
There are almost no changes to nushell itself, all changes are contained
within `nu-json` crate (minus any documentation updates).

Oh, almost forgot to mention, to get the tests compiling, I added
fancy_regex as a _dev_ dependency to nu-json. I could look into
eliminating that if desirable.

# User-Facing Changes

**Breaking Change**
nushell now outputs the desired result using the reproduction command
from the issue:
```
echo '{"version": "v0.4.4","notes": "blablabla","pub_date": "2024-05-04T16:05:00Z","platforms":{"windows-x86_64":{"signature": "blablabla","url": "https://blablabla"}}}' | from json | to json
```

outputs:
```
{
  "version": "v0.4.4",
  "notes": "blablabla",
  "pub_date": "2024-05-04T16:05:00Z",
  "platforms": {
    "windows-x86_64": {
      "signature": "blablabla",
      "url": "https://blablabla"
    }
  }
}
```

whereas previously it would push the opening braces onto a new line:
```
{
  "version": "v0.4.4",
  "notes": "blablabla",
  "pub_date": "2024-05-04T16:05:00Z",
  "platforms":
  {
    "windows-x86_64":
    {
      "signature": "blablabla",
      "url": "https://blablabla"
    }
  }
}
```

# Tests + Formatting

toolkit check pr mostly passes - there are regrettably some tests not
passing on my windows machine _before making any changes_ (I may look
into this as a separate issue)

I have re-enabled the [hjson
tests](https://github.com/nushell/nushell/blob/main/crates/nu-json/tests/main.rs).
This is done in the second commit 🙂 
They have a crucial difference to what they were previously asserting:
  * nu-json outputs in json syntax, not hjson syntax
I think this is desirable, but I'm not aware of the history of these
tests.

# After Submitting

I suspect there `to json` command examples will need updating to match,
haven't checked yet!

Report parse warns and compile errs when running script files (#13369)
# Description

Report parse warnings and compile errors when running script files.

It's useful to report this information to script authors and users so
they can know if they need to update something in the near future.

I also found that moving some errors from eval to compile time meant
some error tests can fail (in `tests/repl`) so this is a good idea to
keep those passing.

Fix select cell path renaming behavior (#13361)
# Description

Fixes #13359

In an attempt to generate names for flat columns resulting from a nested
accesses #3016 generated new column names on nested selection, out of
convenience, that composed the cell path as a string (including `.`) and
then simply replaced all `.` with `_`. As we permit `.` in column names
as long as you quote this surprisingly alters `select`ed columns.


# User-Facing Changes
New columns generated by selection with nested cell paths will for now
be named with a string containing the keys separated by `.` instead of
`_`. We may want to reconsider the semantics for nested access.

Add IR support to the debugger (#13345)
# Description

This adds tracing for each individual instruction to the `Debugger`
trait. Register contents can be inspected both when entering and leaving
an instruction, and if an instruction produced an error, a reference to
the error is also available. It's not the full `EvalContext` but it's
most of the important parts for getting an idea of what's going on.

Added support for all of this to the `Profiler` / `debug profile` as
well, and the output is quite incredible - super verbose, but you can
see every instruction that's executed and also what the result was if
it's an instruction that has a clearly defined output (many do).

# User-Facing Changes

- Added `--instructions` to `debug profile`, which adds the `pc` and
`instruction` columns to the output.
- `--expr` only works in AST mode, and `--instructions` only works in IR
mode. In the wrong mode, the output for those columns is just blank.

Fix order of I/O types in take until (#13356)
# Description
Just a quick one, but `List(Any)` has to come before `Table`, because
`List(Any)` is a valid match for `Table`, so it will choose `Table`
output even if the input was actually `List(Any)`. I ended up removing
`Table` because it's just not needed at all anyway.

Though, I'm not really totally sure this is correct - I think the parser
should probably actually just have some idea of what the more specific
type is, and choose the most specific type match, rather than just doing
it in order. I guess this will result in the output just always being
`List(Any)` for now. Still better than a bad typecheck error

# User-Facing Changes

Fixes the following contrived example:

```nushell
def foo []: nothing -> list<int> {
  seq 1 10 | # list<int>
    each { |n| $n * 20 } | # this causes the type to become list<any>
    take until { |x| $x < 10 } } # table is first, so now this is type table
    # ...but table is not compatible with list<int>
}

Update config directly at assignment (#13332)
# Description

Allows `Stack` to have a modified local `Config`, which is updated
immediately when `$env.config` is assigned to. This means that even
within a script, commands that come after `$env.config` changes will
always see those changes in `Stack::get_config()`.

Also fixed a lot of cases where `engine_state.get_config()` was used
even when `Stack` was available.

Closes #13324.

# User-Facing Changes
- Config changes apply immediately after the assignment is executed,
rather than whenever config is read by a command that needs it.
- Potentially slower performance when executing a lot of lines that
change `$env.config` one after another. Recommended to get `$env.config`
into a `mut` variable first and do modifications, then assign it back.
- Much faster performance when executing a script that made
modifications to `$env.config`, as the changes are only parsed once.

Add more argument types to view ir (#13343)
# Description

Add a few more options to `view ir` for finding blocks, which I found
myself wanting while trying to trace through the generated code.

If we end up adding support for plugins to call commands that are in
scope by name, this will also make it possible for
`nu_plugin_explore_ir` to just step through IR automatically (by passing
the block/decl ids) without exposing too many internals. With that I
could potentially add keys that allow you to step in to closures or
decls with the press of a button, just by calling `view ir --json`
appropriately.

# User-Facing Changes

- `view ir` can now take names of custom commands that are in scope.
- integer arguments are treated as block IDs, which sometimes show up in
IR (closure, block, row condition literals).
- `--decl-id` provided to treat the argument as a decl ID instead, which
is also sometimes necessary to access something that isn't in scope.

Use Arc for environment variables on the stack (#13333)
# Description

This is another easy performance lift that just changes `env_vars` and
`env_hidden` on `Stack` to use `Arc`. I noticed that these were being
cloned on essentially every closure invocation during captures
gathering, so we're paying the cost for all of that even when we don't
change anything. On top of that, for `env_vars`, there's actually an
entirely fresh `HashMap` created for each child scope, so it's highly
unlikely that we'll modify the parent ones.

Uses `Arc::make_mut` instead to take care of things when we need to
mutate something, and most of the time nothing has to be cloned at all.

# Benchmarks

The benefits are greater the more calls there are to env-cloning
functions like `captures_to_stack()`. Calling custom commands in a loop
is basically best case for a performance improvement. Plain `each` with
a literal block isn't so badly affected because the stack is set up

Better performance, particularly for custom commands, especially if
there are a lot of environment variables. Nothing else.

Internal representation (IR) compiler and evaluator (#13330)
# Description

This PR adds an internal representation language to Nushell, offering an
alternative evaluator based on simple instructions, stream-containing
registers, and indexed control flow. The number of registers required is
determined statically at compile-time, and the fixed size required is
allocated upon entering the block.

Each instruction is associated with a span, which makes going backwards
from IR instructions to source code very easy.

Motivations for IR:

1. **Performance.** By simplifying the evaluation path and making it
more cache-friendly and branch predictor-friendly, code that does a lot
of computation in Nushell itself can be sped up a decent bit. Because
the IR is fairly easy to reason about, we can also implement
optimization passes in the future to eliminate and simplify code.
2. **Correctness.** The instructions mostly have very simple and
easily-specified behavior, so hopefully engine changes are a little bit
easier to reason about, and they can be specified in a more formal way
at some point. I have made an effort to document each of the
instructions in the docs for the enum itself in a reasonably specific
way. Some of the errors that would have happened during evaluation
before are now moved to the compilation step instead, because they don't
make sense to check during evaluation.
3. **As an intermediate target.** This is a good step for us to bring
the [`new-nu-parser`](https://github.com/nushell/new-nu-parser) in at
some point, as code generated from new AST can be directly compared to
code generated from old AST. If the IR code is functionally equivalent,
it will behave the exact same way.
4. **Debugging.** With a little bit more work, we can probably give
control over advancing the virtual machine that `IrBlock`s run on to
some sort of external driver, making things like breakpoints and single
stepping possible. Tools like `view ir` and [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir) make it easier than
before to see what exactly is going on with your Nushell code.

The goal is to eventually replace the AST evaluator entirely, once we're
sure it's working just as well. You can help dogfood this by running
Nushell with `$env.NU_USE_IR` set to some value. The environment
variable is checked when Nushell starts, so config runs with IR, or it
can also be set on a line at the REPL to change it dynamically. It is
also checked when running `do` in case within a script you want to just
run a specific piece of code with or without IR.

# Example

```nushell
view ir { |data|
  mut sum = 0
  for n in $data {
    $sum += $n
  }
  $sum
}
```
  
```gas
# 3 registers, 19 instructions, 0 bytes of data
   0: load-literal           %0, int(0)
   1: store-variable         var 904, %0 # let
   2: drain                  %0
   3: drop                   %0
   4: load-variable          %1, var 903
   5: iterate                %0, %1, end 15 # for, label(1), from(14:)
   6: store-variable         var 905, %0
   7: load-variable          %0, var 904
   8: load-variable          %2, var 905
   9: binary-op              %0, Math(Plus), %2
  10: span                   %0
  11: store-variable         var 904, %0
  12: load-literal           %0, nothing
  13: drain                  %0
  14: jump                   5
  15: drop                   %0          # label(0), from(5:)
  16: drain                  %0
  17: load-variable          %0, var 904
  18: return                 %0
```

# Benchmarks

All benchmarks run on a base model Mac Mini M1.

## Iterative Fibonacci sequence

This is about as best case as possible, making use of the much faster
control flow. Most code will not experience a speed improvement nearly
this large.

```nushell
def fib [n: int] {
  mut a = 0
  mut b = 1
  for _ in 2..=$n {
    let c = $a + $b
    $a = $b
    $b = $c
  }
  $b
}
use std bench
bench { 0..50 | each { |n| fib $n } }
```

[random-bytes.nu](https://github.com/nushell/nu_scripts/blob/main/benchmarks/random-bytes.nu)

I got pretty random results out of this benchmark so I decided not to
include it. Not clear why.

# User-Facing Changes
- IR compilation errors may appear even if the user isn't evaluating
with IR.
- IR evaluation can be enabled by setting the `NU_USE_IR` environment
variable to any value.
- New command `view ir` pretty-prints the IR for a block, and `view ir
--json` can be piped into an external tool like [`explore
ir`](https://github.com/devyn/nu_plugin_explore_ir).

# Tests + Formatting
All tests are passing with `NU_USE_IR=1`, and I've added some more eval
tests to compare the results for some very core operations. I will
probably want to add some more so we don't have to always check
`NU_USE_IR=1 toolkit test --workspace` on a regular basis.

# After Submitting
- [ ] release notes
- [ ] further documentation of instructions?
- [ ] post-release: publish `nu_plugin_explore_ir`

Make pipe redirections consistent, add err>| etc. forms (#13334)
# Description

Fixes the lexer to recognize `out>|`, `err>|`, `out+err>|`, etc.

Previously only the short-style forms were recognized, which was
inconsistent with normal file redirections.

I also integrated it all more into the normal lex path by checking `|`
in a special way, which should be more performant and consistent, and
cleans up the code a bunch.

Closes #13331.

# User-Facing Changes
- Adds `out>|` (error), `err>|`, `out+err>|`, `err+out>|` as recognized
forms of the pipe redirection.

# Tests + Formatting
All passing. Added tests for the new forms.

Fix main binary being rebuilt when nothing has changed (#13337)
# 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 build script is currently re-run on each `cargo build` even when it
has not changed. The `rerun-if-changed` line points to `/build.rs`, but
`build.rs` is actually located at `/scripts/build.rs`. This updates that
path.

Make polars unpivot consistent with polars pivot (#13335)
# Description
Makes `polars unpivot` use the same arguments as `polars pivot` and
makes it consistent with the polars' rust api. Additionally, support for
the polar's streaming engine has been exposed on eager dataframes.
Previously, it would only work with lazy dataframes.


# User-Facing Changes
* `polars unpivot` argument `--columns`|`-c` has been renamed to
`--index`|`-i`
* `polars unpivot` argument `--values`|`-v` has been renamed to
`--on`|`-o`
* `polars unpivot` short argument for `--streamable` is now `-t` to make
it consistent with `polars pivot`. It was made `-t` for `polars pivot`
because `-s` is short for `--short`
