When the user selected a custom agent (e.g. Codex) and chose 'Start
Thread in New Worktree', the new workspace's panel ignored the selection
and defaulted to Zed Agent.

The fix captures self.selected_agent() in handle_worktree_creation_requested
before the async task, passes it through to setup_new_workspace, and
forwards it to external_thread instead of None.

With these newer models that come with different thinking levels, it's
become more frequent to want to see what the thinking is outputting.
Thus far in Zed, the thinking block would show up automatically
collapsed and every time you wanted to see it, you had to expand it
manually. This PR changes that by making the thinking block
automatically _expanded_ instead, but as soon as it's done, it collapses
again.

Release Notes:

- Agent: Improved visibility of thinking blocks by making them
auto-expanded while in progress.

Two changes to support pushing `/docs/ai/tools` into the top 10 for
"agent tools" (8,900 monthly volume, currently position 11).

**`docs/src/ai/tools.md`** — adds a concrete usage example to 7 tools:
`diagnostics`, `grep`, `fetch`, `edit_file`, `terminal`, `web_search`,
and `subagent`. Each example shows a realistic scenario rather than
restating the description.

**`docs/src/ai/external-agents.md`** — adds a single sentence
cross-linking to `tools.md` after the supported-agents intro paragraph,
for users who land on that page looking for what the built-in agent can
do.

Closes #51297

On non-QWERTY layouts, all Cmd+key events are routed through the macOS
IME because `key_char` is always `None` when Cmd is held. For certain
characters (dead keys like backtick, and non-dead keys like ç), the IME
calls `insertText:` instead of `doCommandBySelector:`, consuming the
event before it reaches GPUI's keybinding system or macOS system
shortcuts.

This adds `!platform` to the IME-path condition in `handle_key_event` so
Cmd+key events bypass the IME (except when composing). GPUI handles them
if a binding matches, otherwise `performKeyEquivalent:` returns `NO` and
macOS handles them.

**This won't fully fix Cmd+backtick window cycling by itself** because
Zed's key_equivalents system maps default keybindings onto the physical
backtick key on various layouts. For example, `cmd-'`
(ToggleSelectedDiffHunks) maps to the backtick key on Spanish, `cmd-=`
(IncreaseBufferFontSize) on Scandinavian layouts, `cmd-"`
(ExpandAllDiffHunks) on German/Portuguese/Swiss, and `cmd-}`
(ActivateNextItem) on Spanish-ISO. These Zed bindings shadow the
backtick key and consume the event before macOS can cycle windows. I'd
appreciate guidance on the preferred approach to resolve these
keybinding conflicts -- IMO, Zed's default shortcuts should not be
interfering with Cmd+backtick for any layout.

Release Notes:

- Fixed Cmd+key shortcuts being consumed by the IME on non-QWERTY
keyboard layouts, preventing Zed keybindings and macOS system shortcuts
from working with special characters.

Previously, if you wanted to have a button that contains icons on both
edges, you'd need to use a `ButtonLike` component, which takes any
children. Meanwhile, the `Button` would only take one icon, where you
could control its position through the `IconPosition` enum. This has
always felt unnecessarily limiting. So, this PR removes this limitation
by adding two new methods to the button: `start_icon` and `end_icon`.

In the meantime, I have also been bothered by the unnecessary
indirection in the `IconButton` due to the existence of the `ButtonIcon`
component. So I figured I could also completely eliminate that by adding
some of its methods directly to the `IconButton` and in the Button, just
using a regular `Icon` component.

---
## Before
```rust
Button::new("id", "Label")
    .icon(IconName::Plus)
    .icon_position(IconPosition::Start)
    .icon_size(IconSize::Small)
    .icon_color(Color::Muted)
```

## After
```rust
Button::new("id", "Label")
    .start_icon(Icon::new(IconName::Check))
    .end_icon(Icon::new(IconName::ChevronDown).size(IconSize::XSmall))
```

This should have no visual impact to the UI.

When the connection to X is broken zed will go into an infinite loop and
eat up 100% (of one core) of CPU; this change causes it to exit with an
error instead.

I encountered this behavior while running zed in
[Xephyr](https://freedesktop.org/wiki/Software/Xephyr/) for testing,
though I do sometimes terminate my X server as a way to log out or
attempt to recover from a (very) broken state, and I appreciate a
graceful exit in those situations!

Exiting in case of X server disconnect is common practice in my
observations, likely as the difficulty of recreating state stored
server-side outweighs the potential utility in attempting to recover (if
"reconnecting" to an X server is ever desired in regular usage,
[Xpra](https://xpra.org/index.html) might be able to help!).

This PR introduces the `project_panel.scrollbar.horizontal_scroll`
setting to allow users to toggle the horizontal scroll bar in the
project panel. This was Zed's design before PR #18513, and the default
behavior of VSCode (`workbench.list.horizontalScrolling`).


https://github.com/user-attachments/assets/f633f4e4-a585-4494-8f48-df77c6aca418

## Rationale

Zed's design used to be the same as the default behavior of VSCode.
I.e., no horizontal scrolling, and the view is always snapped to the
left, with long file names clipped of. If you want to see the content
that is out-of-frame, you'll need to drag the handle and expand the
project panel. This could be problematic, especially for large repos
with multiple levels of nested directories, as pointed out by issues
#5550 and #7001.

<img width="1398" height="992" alt="image"
src="https://github.com/user-attachments/assets/d86563f2-0f06-4e9e-818c-155ac45f0f56"
/>\
*VSCode's default setup, for reference.*

Then came PR #18513, which added horizontal scroll and addressed this
pain point, but users didn't have a choice. They're stuck with
horizontal scrolling always turned on. I, for instance, personally
prefer the old, VSCode-default behavior, for most projects I open are
small and don't need horizontal scrolling in the project panel. With
horizontal scrolling always turned on, I find it annoying to have my
project panel view accidentally scrolled to the middle, and I'll have to
grab my mouse and scroll it back. It's also visually redundant.

Thus, why not add an option like VSCode's
`workbench.list.horizontalScrolling` and let users choose? I'd love to
be able to, say, set a per-project override for the projects that need
horizontal scrolling, while having it disabled by default.

## Extra Notes

- I was originally thinking about using `ScrollbarAxes` from
`src/editor_settings.rs` and make the option
`project_panel.scrollbar.axes.horizontal` similar to the global editor
scrollbar settings, but this option is specific to the project panel and
it doesn't quite make sense to allow disabling vertical scrolling on the
project panel, so I added a standalone option for it instead, similar to
VSCode's `workbench.list.horizontalScrolling`.

- I went the conservative route and set horizontal scrolling to enabled
(current behavior) by default. Imo it might make more sense to disable
it by default instead, similar to VSCode, but I'll leave this for the
Zed team to decide.

- I named it `horizontal_scroll` instead of `horizontal_scrolling` to be
consistent with the adjacent setting `sticky_scroll`.

- As for tests, I don't see tests for the scrollbar, so I didn't add
any.

I'd be glad to update the PR if anything is not inline with the
project's requirements or conventions.

- Added `project_panel.scrollbar.horizontal_scroll` setting to allow

When on a untrusted project, if one was to try and use the commit
generation functionality, the command would fail because of the `-c
diff.external` configuration provided in `GitBinary::build_command`, as
git would interpret this as `""` and try to run that command.

This `-c diff.external` is a good safeguard to have on untrusted
repositories because it prevents random commands, configured in
`.git/config` from being run. For example, if one uses `git config
diff.external "touch bananas.txt"` and then run `git diff`, a new
`bananas.txt` file would be created.

However, it was still possible to bypass this safeguard using the
following strategy:

1. Specify a custom diff for a specific file format. For example, for
markdown files, with `printf '*.md diff=pwned\n' > .gitattributes`
2. Update the command run by the `pwned` diff, for example, `git config
diff.pwned.command "touch bananas.txt"`
3. Open Zed and attempt to generate a commit message in an untrusted
repository and check that a new `bananas.txt` file was created

This is only prevented by using the `--no-ext-diff` flag on the `diff`
command, so a new `GitBinary::build_diff_command` has been introduced
which simply wraps `GitBinary::build_command` and adds the
`--no-ext-diff` flag, if necessary.

As a side-effect, this also makes it so that generating a commit message
in an untrusted repository works again, which was accidentally broken on
https://github.com/zed-industries/zed/pull/50649 .

Closes #51450 

When you restart the lsp, it does not sufficiently clear cached data
regarding the semantic tokens, if using semantic_tokens = "full", this
would mean that you would have no syntax highlighting. also, toggling on
and off semantic tokens in the menu would have no effect. this change
properly clears the cached state and things work again!

You might notice that the syntax highlighting is quite spare in the
videos, especially compared to the non semantic token based
highlighting, and you would be correct! but thats just how it is with
`semantic_tokens: "full"`, other editors, like neovim, provide basic
syntax highlighting that zed doesn't (because it doesn't need to with
treesitter usually, but here treesitter is disabled), however if we turn
off that syntax highlighting we can see that neovim actually matches zed
here:
