No longer autoload deprecated-dirs (#14242)
# Description

Follow-up to #13842. In that commit, using one of the `dirs`/`shells`
aliases would notify the user that it would no longer be autoloaded in
future releases. This is the removal stage.

Side-benefit: Additional 1ms+ load time improvement

# User-Facing Changes

Breaking-change - `dirs` aliases are no longer autoloaded.

Users can either choose to continue using the aliases by adding the
following to the startup:

```nu
use std/dirs shells-aliases *
```

Alternatively, users can use the `dirs` subcommands (rather than the
aliases) with:

```nu
use std/dirs
```

Virtual std module subdirectories (#14040)
# Description

Uses "normal" module `std/<submodule>/mod.nu` instead of renaming the

Fix dirs removal warning (#14029)
# Description

* Primary purpose is to fix an issue with a missing escaped opening
parenthesis in the warning message when running an old `dirs` alias.
This was creating an error condition from improper interpolation.

Also

* Incorporates #13842 feedback from @kubouch by renaming `std/lib` to
`std/util`
* Removes duplication of code in `export-env`
* Renames submodule exports to `std/<submodule>` rather than
`./<submodule>` - No user-facing change other than `view files` appears
"prettier".
* In #13842, I converted the test cases to use `use std/<module>`
syntax. Previously, the tests were (effectively) using `use std *` (due
to pre-existing bugs, now fixed).

So "before", we only had test coverage on `use std *`, and "after" we
only had test coverage on `use std/<module>`. I've started adding test
cases so that we have coverage on *both* scenarios going forward.

For now, `formats` and `util` have been updated with tests for both
scenarios. I'll continue adding the others in future PRs.

Load env when importing with use std * (#14012)
# Description

After a `use std *`, the environment variables exported from the
submodules' `export-env` blocks are not available because of #13403.
This causes failures in `log` (currently) and will cause issues in
`dirs` once we stop autoloading it separately.

When the submodules are loaded separately (e.g., `use std/log`),
everything already worked correctly. While this is the preferred way of
doing it, we also want `use std *` to work properly.

This is a workaround for the standard library submodules. It is
definitely not ideal, but it can be removed when and if #13403 is fixed.

For now, we need to duplicate any environment settings in both the
submodules (when loaded with `use std/log`) and in the standard library
itself (when loaded with `use std *`). Again, this should not be
necessary, but currently is because of #13403.

Fix namespace collision in std and nupm (#14009)
# Description

Fxes https://github.com/nushell/nupm/issues/102

Not loading `std` at startup has caused an issue with nupm and std where
the `dirs` module name clashes and nupm won't load. This was technically
a preexisting bug that was previously masked. This could have been fixed
(and also should be) by changing the import statement in nupm, but the
potential for collision would remain in other (user) modules.

This PR explicitly sets the relative path for the import statements in
`std/mod.nu` so that there are no collisions.

Improves startup time when using std-lib (#13842)
Updated summary for commit
[612e0e2](612e0e2160)
- While folks are welcome to read through the entire comments, the core
information is summarized here.

# Description

This PR drastically improves startup times of Nushell by only parsing a
single submodule of the Standard Library that provides the `banner` and
`pwd` commands. All other Standard Library commands and submodules are
parsed when imported by the user. This cuts startup times by more than
60%.

At the moment, we have stopped adding to `std-lib` because every
addition adds a small amount to the Nushell startup time.
With this change, we should once again be able to allow new
functionality to be added to the Standard Library without it impacting
`nu` startup times.

# User-Facing Changes

* Nushell now starts about 60% faster
* Breaking change: The `dirs` (Shells) aliases will return a warning
message that it will not be auto-loaded in the following release, along
with instructions on how to restore it (and disable the message)
* The `use std <submodule> *` syntax is available for convenience, but
should be avoided in scripts as it parses the entire `std` module and
all other submodules and places it in scope. The correct syntax to
*just* load a submodule is `use std/<submodule> *` (asterisk optional).
The slash is important. This will be documented.
* `use std *` can be used for convenience to load all of the library but
still incurs the full loading-time.
* `std/dirs`: Semi-breaking change. The `dirs` command replaces the
`show` command. This is more in line with the directory-stack
functionality found in other shells. Existing users will not be impacted
by this as the alias (`shells`) remains the same.

* Breaking-change: Technically a breaking change, but probably only
impacts maintainers of `std`. The virtual path for the standard library
has changed. It could previously be imported using its virtual path (and
technically, this would have been the correct way to do it):

  ```nu
  use NU_STDLIB_VIRTUAL_DIR/std
  ```

  The path is now simply `std/`:

  ```nu
  use std
  ```

  All submodules have moved accordingly.
  

# Timings

Comparisons below were made:

* In a temporary, clean config directory using `$env.XDG_CONFIG_HOME =
(mktemp -d)`.
* `nu` was run with a release build
* `nu` was run one time to generate the default `config.nu` (etc.) files
- Otherwise timings would include the user-prompt
* The shell was exited and then restarted several times to get timing
samples

(Note: Old timings based on 0.97 rather than 0.98, but in the range of
being accurate)

| Scenario | `$nu.startup-time` |
| --- | --- |
| 0.97.2
([aaaab8e](aaaab8e070))
Without this PR | 23ms - 24ms |
| This PR with deprecated commands | 9ms - <11ms |
| This PR after deprecated commands are removed in following release |
8ms - <10ms |
| Final PR (remove deprecated), using `--no-std-lib` | 6.1ms to 6.4ms |
| Final PR (remove deprecated), using `--no-config-file` | 3.1ms - 3.6ms
|
| Final PR (remove deprecated), using `--no-config-file --no-std-lib` |
1ms - 1.5ms |

*These last two timings point to the opportunity for further
optimization (see comment in thread below (will link once I write it).*

# Implementation details for future maintenance

* `use std banner` is a ridiculously deceptive call. That call parses
and imports *all* of `std` into scope. Simply replacing it with `use
std/core *` is essentially what saves ~14-15ms. This *only* imports the
submodule with the `banner` and `pwd` commands.

* From the code-comments, the reason that `NU_STDLIB_VIRTUAL_DIR` was
used as a prefix was so that there wouldn't be an issue if a user had a
`./std/mod.nu` in the current directory. This does **not** appear to be
an issue. After removing the prefix, I tested with both a relative
module as well as one in the `$env.NU_LIB_DIRS` path, and in all cases
the *internal* `std` still took precedence.

* By removing the prefix, users can now `use std` (and variants) without
requiring that it already be parsed and in scope.

* In the next release, we'll stop autoloading the `dirs` (shells)
functionality. While this only costs an additional 1-1.5ms, I think it's
better moved to the `config.nu` where the user can optionally remove it.
The main reason is its use of aliases (which have also caused issues) -
The `n`, `p`, and `g` short-commands are valuable real-estate, and users
may want to map these to something else.
  
For this release, there's an `deprecated_dirs` module that is still
autoloaded. As with the top-level commands, use of these will give a
deprecation warning with instructions on how to handle going forward.

To help with this, moved the aliases to their own submodule inside the
`dirs` module.

* Also sneaks in a small change where the top-level `dirs` command is
now the replacement for `dirs show`

* Fixed a double-import of `assert` in `dirs.nu`
* The `show_banner` step is replaced with simply `banner` rather than
re-importing it.

* A `virtual_path` may now be referenced with either a forward-slash or
a backward-slash on Windows. This allows `use std/<submodule>` to work
on all platforms.

# Performance side-notes:

* Future parsing and/or IR improvements should improve performance even
further.
* While the existing load time penalty of `std-lib` was not noticeable
on many systems, Nushell runs on a wide-variety of hardware and OS
platforms. Slower platforms will naturally see a bigger jump in
performance here. For users starting multiple Nushell sessions
frequently (e.g., `tmux`, Zellij, `screen`, et. al.) it is recommended
to keep total startup time (including user configuration) under ~250ms.

# Tests + Formatting

* All tests are green

* Updated tests:
- Removed the test that confirmed that `std` was loaded (since we
don't).
- Removed the `shells` test since it is not autoloaded. Main `dirs.nu`
functionality is tested through `stdlib-test`.
- Many tests assumed that the library was fully loaded, because it was
(even though we didn't intend for it to be). Fixed those tests.
- Tests now import only the necessary submodules (e.g., `use
std/assert`, rather than `use std assert`)
- Some tests *thought* they were loading `std/log`, but were doing so
improperly. This was masked by the now-fixed "load-everything-into-scope
bug". Local CI would pass due the `$env.NU_LOG_<...>` variables being
inherited from the calling process, but would fail in the "clean" GitHub
CI environment. These tests have also been fixed.

 * Added additional tests for the changes

Set current working directory at startup (#12953)
This PR sets the current working directory to the location of the
Nushell executable at startup, using `std::env::set_current_dir()`. This
is desirable because after PR
https://github.com/nushell/nushell/pull/12922, we no longer change our
current working directory even after `cd` is executed, and some OS might
lock the directory where Nushell started.

The location of the Nushell executable is chosen because it cannot be
removed while Nushell is running anyways, so we don't have to worry
about OS locking it.

This PR has the side effect that it breaks buggy command even harder.
I'll keep this PR as a draft until these commands are fixed, but it
might be helpful to pull this PR if you're working on fixing one of
those bugs.

Error on non-zero exit statuses (#13515)
# Description
This PR makes it so that non-zero exit codes and termination by signal
are treated as a normal `ShellError`. Currently, these are silent
errors. That is, if an external command fails, then it's code block is
aborted, but the parent block can sometimes continue execution. E.g.,
see #8569 and this example:
```nushell
[1 2] | each { ^false }
```

Before this would give:
```
╭───┬──╮
│ 0 │  │
│ 1 │  │
╰───┴──╯
```

Now, this shows an error:
```
Error: nu:🐚:eval_block_with_input

  × Eval block failed with pipeline input
   ╭─[entry #1:1:2]
 1 │ [1 2] | each { ^false }
   ·  ┬
   ·  ╰── source value
   ╰────

Error: nu:🐚:non_zero_exit_code

  × External command had a non-zero exit code
   ╭─[entry #1:1:17]
 1 │ [1 2] | each { ^false }
   ·                 ──┬──
   ·                   ╰── exited with code 1
   ╰────
```

This PR fixes #12874, fixes #5960, fixes #10856, and fixes #5347. This
PR also partially addresses #10633 and #10624 (only the last command of
a pipeline is currently checked). It looks like #8569 is already fixed,
but this PR will make sure it is definitely fixed (fixes #8569).

# User-Facing Changes
- Non-zero exit codes and termination by signal now cause an error to be
thrown.
- The error record value passed to a `catch` block may now have an
`exit_code` column containing the integer exit code if the error was due
to an external command.
- Adds new config values, `display_errors.exit_code` and
`display_errors.termination_signal`, which determine whether an error
message should be printed in the respective error cases. For
non-interactive sessions, these are set to `true`, and for interactive
sessions `display_errors.exit_code` is false (via the default config).

# Tests
Added a few tests.

# After Submitting
- Update docs and book.
- Future work:
- Error if other external commands besides the last in a pipeline exit
with a non-zero exit code. Then, deprecate `do -c` since this will be
the default behavior everywhere.
- Add a better mechanism for exit codes and deprecate
`$env.LAST_EXIT_CODE` (it's buggy).

Setup global cargo lint configuration (#13691)
# Description
`cargo` somewhat recently gained the capability to store `lints`
settings for the crate and workspace, that can override the defaults
from `rustc` and `clippy` lints. This means we can enforce some lints
without having to actively pass them to clippy via `cargo clippy -- -W
...`. So users just forking the repo have an easier time to follow
similar requirements like our CI.

## Limitation

An exception that remains is that those lints apply to both the primary
code base and the tests. Thus we can't include e.g. `unwrap_used`
without generating noise in the tests. Here the setup in the CI remains
the most helpful.

## Included lints

- Add `clippy::unchecked_duration_subtraction` (added by #12549)
# User-Facing Changes
Running `cargo clippy --workspace` should be closer to the CI. This has
benefits for editor configured runs of clippy and saves you from having
to use `toolkit` to be close to CI in more cases.

Change behavior of into record on lists to be more useful (#13637)
# Description

The previous behaviour of `into record` on lists was to create a new
record with each list index as the key. This was not very useful for
creating meaningful records, though, and most people would end up using
commands like `headers` or `transpose` to turn a list of keys and values
into a record.

This PR changes that instead to do what I think the most ergonomic thing
is, and instead:

- A list of records is merged into one record.
- A list of pairs (two element lists) is folded into a record with the
first element of each pair being the key, and the second being the
value.

The former is just generally more useful than having to use `reduce`
with `merge` for such a common operation, and the latter is useful
because it means that `$a | zip $b | into record` *just works* in the
way that seems most obvious.

Example:

```nushell
[[foo bar] [baz quux]] | into record # => {foo: bar, baz: quux}
[{foo: bar} {baz: quux}] | into record # => {foo: bar, baz: quux}
[foo baz] | zip [bar quux] | into record # => {foo: bar, baz: quux}
```

The support for range input has been removed, as it would no longer
reflect the treatment of an equivalent list.

The following is equivalent to the old behavior, in case that's desired:

```
0.. | zip [a b c] | into record # => {0: a, 1: b, 2: c}
```

# User-Facing Changes
- `into record` changed as described above (breaking)
- `into record` no longer supports range input (breaking)

# Tests + Formatting
Examples changed to match, everything works. Some usage in stdlib and
`nu_plugin_nu_example` had to be changed.

fix: Make log respect use_ansi_coloring setting. (#13442)
# Very briefly
Fixes: #13317 
- Ignore ansi coloring on logs if this setting is true.
- Add a reset after the default left prompt (before prompt character)
which fixes all-red text when `use_ansi_coloring` is false.

# Description

## Firstly,
argumentation about the changes to `crates/nu-std/std/log.nu`

Previous behavior colored the output of all log, even when the setting
`use_ansi_coloring` was false.

![image](https://github.com/user-attachments/assets/a82991c4-ff46-455d-8dac-248de2456d78)

Current behavior honors the setting.

![image](https://github.com/user-attachments/assets/6d5365db-e05d-4d2a-8981-f22303dff081)

## Second,
While testing different scenarios, I found out that the default setting
on both (`0.95`, arch linux) and the source (`0.96`) all text was
displayed in red (the color used for the present-working-directory part
of the prompt) after setting `use_ansi_coloring` to `false` ([comment
with picture of the issue and reproduction
steps](https://github.com/nushell/nushell/issues/13317#issuecomment-2247439894)).
To which my response was adding a `(ansi reset)` at the end of the
directory part of the prompt in the default config
(`crates/nu-utils/src/sample_config/default_env.nu`) file. All later
parts follow the `use_ansi_coloring` setting and their assigned colors.

# User-Facing Changes
I would say the color, but don't know if that counts as "user-facing".

# Tests + Formatting
- Formatting was applied as advised.
- 1314 tests passed and 24 ignored, none failed.
- Clippy  did not pass due to an error on the following files:
`crates/nu-protocol/src/engine/argument.rs:81:5` and
`crates/nu-protocol/src/engine/error_handler.rs:19:5`
throwing the error `you should consider adding a 'Default'
implementation for 'ErrorHandlerStack'`.
As those files are out of the scope of the current issue, they have
**not** been changed.

don't show result in error make examples (#13296)
# Description
Fixes: #13189 

The issue is caused `error make` returns a `Value::Errror`, and when
nushell pass it to `table -e` in `std help`, it directly stop and render
the error message.
To solve it, I think it's safe to make these examples return None
directly, it doesn't change the reult of `help error make`.

Fix do signature (#13216)
Recommend holding until after #13125 is fully digested and *possibly*
until 0.96.

# Description

Fixes one of the issues described in #13125 

The `do` signature included a `SyntaxShape:Any` as one of the possible
first-positional types. This is incorrect. `do` only takes a closure as
a positional. This had the result of:

1. Moving what should have been a parser error to evaluation-time

   ## Before

   ```nu
   > do 1
   Error: nu:🐚:cant_convert

     × Can't convert to Closure.
      ╭─[entry #26:1:4]
    1 │ do 1
      ·    ┬
      ·    ╰── can't convert int to Closure
      ╰────
   ```

   ## After

   ```nu
   > do 1
   Error: nu::parser::parse_mismatch

     × Parse mismatch during operation.
      ╭─[entry #5:1:4]
    1 │ do 1
      ·    ┬
      ·    ╰── expected block, closure or record
      ╰────
   ```  

2. Masking a bad test in `std assert`

This is a bit convoluted, but `std assert` tests included testing
`assert error` to make sure it:

* Asserts on bad code
* Doesn't assert on good code

The good-code test was broken, and was essentially bad-code (really
bad-code) that wasn't getting caught due to the bad signature.

Fixing this resulted in *parse time* failures on every call to
`test_asserts` (not something that particular test was designed to
handle.

This PR also fixes the test case to properly evaluate `std assert error`
against a good code path.

Surprising symlink resolution for std path add (#13258)
# Description
The standard library's `path add` function has some surprising side
effects that I attempt to address in this PR:

1. Paths added, if they are symbolic links, should not be resolved to
their targets. Currently, resolution happens.

   Imagine the following:

   ```nu
# Some time earlier, perhaps even not by the user, a symlink is created
   mkdir real-dir
   ln -s real-dir link-dir

   # Then, step to now, with link-dir that we want in our PATHS variable
   use std
   path add link-dir
   ```

In the current implementation of `path add`, it is _not_ `link-dir` that
will be added, as has been stated in the command. It is instead
`real-dir`. This is surprising. Users have the agency to do this
resolution if they wish with `path expand` (sans a `--no-symlink` flag):
for example, `path add (link-dir | path expand)`

In particular, when I was trying to set up
[fnm](https://github.com/Schniz/fnm), a Node.js version manager, I was
bitten by this fact when `fnm` told me that an expected path had not
been added to the PATHS variable. It was looking for the non-resolved
link. The user in [this
comment](https://github.com/Schniz/fnm/issues/463#issuecomment-1710050737)
was likely affected by this too.

Shells, such as nushell, can handle path symlinks just fine. Binary
lookup is unaffected. Let resolution be opt-in.

Lastly, there is some convention already in place for **not** resolving
path symlinks in the [default $env.ENV_CONVERSIONS
table](57452337ff/crates/nu-utils/src/sample_config/default_env.nu (L65)).
   
2. All existing paths in the path variable should be left untouched.
Currently, they are `path expand`-ed (including symbolic link
resolution).

   Path add should mean just that: prepend/append this path.

Instead, it currently means that, _plus mutate all other paths in the
variable_.

Again, users have the agency to do this with something like `$env.PATH =
$env.PATH | split row (char esep) | path expand`.

3. Minorly, I update documentation on running tests in
`crates/nu-std/CONTRIBUTING.md`. The offered command to run the standard
library test suite was no longer functional. Thanks to @weirdan in [this
Discord
conversation](https://discord.com/channels/601130461678272522/614593951969574961/1256029201119576147)
for the context.

# User-Facing Changes

(Written from the perspective of release notes)

- The standard library's `path add` function no longer resolves symlinks
in either the newly added paths, nor the other paths already in the
variable.

# Tests + Formatting

A test for the changes working correctly has been added to
`crates/nu-std/tests/test_std.nu` under the test named
`path_add_expand`.

You can quickly verify this new test and the existing `path add` test
with the following command:

```nu
cargo run -- -c 'use crates/nu-std/testing.nu; NU_LOG_LEVEL=INFO testing run-tests --path crates/nu-std --test path_add'
```

All commands suggested in the issue template have been run and complete
without error.

Expand tables in help examples in std (#13146)
# Description

Some command help has example results with nested `table` data which is
displayed as the "non-expanded" form. E.g.:

```nu
╭───┬────────────────╮
│ 0 │ [list 2 items] │
│ 1 │ [list 2 items] │
╰───┴────────────────╯
```

For a good example, see `help zip`.

While we could simply remove the offending Example `result`'s from the
command itself, `std help` is capable of expanding the table properly.
It already formats the output of each example result using `table`, so
simply making it a `table -e` fixes the output.

While I wish we had a way of expanding the tables in the builtin `help`,
that seems to be the same type of problem as in formatting the `cal`
output (see #11954).

I personally think it's better to add this feature to `std help` than to
remove the offending example results, but as long as `std help` is
optional, only a small percentage of users are going to see the
"expected" results.

# User-Facing Changes

Fixed help for banner (#13138)
# Description

`help banner` had several issues:

* It used a Markdown link to an Asciinema recording, but Markdown links
aren't rendered as Markdown links by the help system (and can't be,
since (most?) terminals don't support that)
* Minor grammatical issues
* The Asciinema recording is out of date anyway. It still uses `use
stdn.nu banner` which isn't valid syntax any longer.

Since everyone at this point knows exactly what `banner` does 😉, I chose
to simply remove the link to the recording. Also tweaked the text
(initial caps and removed comma).

Migrate to a new PWD API (part 2) (#12749)
Refer to #12603 for part 1.

We need to be careful when migrating to the new API, because the new API
has slightly different semantics (PWD can contain symlinks). This PR
handles the "obviously safe" part of the migrations. Namely, it handles
two specific use cases:

* Passing PWD into `canonicalize_with()`
* Passing PWD into `EngineState::merge_env()`

The first case is safe because symlinks are canonicalized away. The
second case is safe because `EngineState::merge_env()` only uses PWD to
call `std::env::set_current_dir()`, which shouldn't affact Nushell. The
commit message contains detailed stats on the updated files.

Because these migrations touch a lot of files, I want to keep these PRs
small to avoid merge conflicts.
