## Summary
This PR extends the `always_allow` tool permission patterns to work with
Nushell, Elvish, and Rc shells. Previously, these shells were
incorrectly excluded because they don't use `&&`/`||` operators for
command chaining. However, brush-parser can safely parse their command
syntax since they all use `;` for sequential execution.
## Changes
- Add `ShellKind::Nushell`, `ShellKind::Elvish`, and `ShellKind::Rc` to
`supports_posix_chaining()`
- Split `ShellKind::Unknown` into `ShellKind::UnknownWindows` and
`ShellKind::UnknownUnix` to preserve platform-specific fallback behavior
while still denying `always_allow` patterns for unrecognized shells
- Add comprehensive tests for the new shell support
- Clarify documentation about shell compatibility
## Shell Notes
- **Nushell**: Uses `;` for sequential execution. The `and`/`or`
keywords are boolean operators on values, not command chaining.
- **Elvish**: Uses `;` to separate pipelines. Does not have `&&` or `||`
operators. Its `and`/`or` are special commands operating on values.
- **Rc (Plan 9)**: Uses `;` for sequential execution and `|` for piping.
Does not have `&&`/`||` operators.
## Security
Unknown shells still return `false` from `supports_posix_chaining()`, so
`always_allow` patterns are denied for safety when we can't verify the
shell's syntax.
(No release notes because granular tool permissions are still
feature-flagged.)

The bug occurred because `smol::process::Command::from(_)` doesn't set
the correct fields for stdio markers. So moving the stdio configuration
after converting to a `smol` command fixed the issue.
I added the `std::process::Command::{stdout, stderr, stdin}` functions
to our disallowed list in clippy to prevent any bugs like this appearing
in the future.

Using `shlex` unconditionally is dangerous as it assumes the underlying
shell is POSIX which is not the case for PowerShell, CMD, or Nushell.
Therefore, whenever we want to quote the args we should utilise our
helper `util::shell::ShellKind::try_quote` which takes into account
which shell is being used to actually exec/spawn the invocation.

Closes#39614
The `ShellKind` struct is built on Windows' side, meaning that when
connecting to remotes, we fall back to PowerShell construction, even if
the shell program we are spawning is a unix program.
This broke tasks creation since we are using the shell kind to construct
args:

In normal terminals this only affected activation scripts (only place
where shell kind is used)
I don't have a Windows machine to test it, so I would appreciate any
help with testing!
Release Notes:
- Fixed an issue where tasks could not be executed in Windows WSL

When sourcing the project environment for the terminal tool, we will now
do so by spawning the shell specified by the users `terminal.shell`
setting (or as usual fall back to the login shell).

std commands can block for an arbitrary duration and so runs risk of
blocking tasks for too long. This replaces all such uses where sensible
with async processes.

Follow-up to: https://github.com/zed-industries/zed/pull/32637
When Zed is installed in a path containing spaces (e.g.,
`/Applications/Zed Nightly.app/Contents/MacOS/zed`), environment
variable loading fails and leaves this in the Zed log:
```
login shell exited with exit status: 127. stdout: "", stderr: "Nightly.app/Contents/MacOS/zed --printenv >&0: /Applications/Zed: No such file or directory"
```
This was not part a release (only broke in nightly), but fixes it the
issue in any case when the path to the Zed.app bundle has a space (e.g.
"Zed Nightly.app")

Zed’s current method of loading environment variables from the login
shell has two issues:
1. Some shells—fish in particular—write specific escape characters to
`stdout` right before they exit. When this happens, the tail end of the
last environment variable printed by `/usr/bin/env` becomes corrupted.
2. If a multi-line value contains an equals sign, that line is
mis-parsed as a separate name-value pair.
This PR addresses those problems by:
1. Redirecting the shell command's `stdout` directly to a temporary
file, eliminating any side effects caused by the shell itself.
2. Replacing `/usr/bin/env` with `sh -c 'export -p'`, which removes
ambiguity when handling multi-line values.
Additional changes:
- Correctly set the arguments used to launch a login shell under `csh`
or `tcsh`.
- Deduplicate code by sharing the implementation that loads environment
variables on first run with the logic that reloads them for a project.
