This pull request enhances syntax highlighting for JavaScript,
TypeScript, TSX, and JSDoc by adding more precise rules for parameters,
types, and punctuation.

- Added queries for highlighting parameters (`@variable.parameter`)
- Expanded highlighting for type identifiers, type aliases, interfaces,
classes
- Extended/implemented types to improve distinction between different
type constructs (`@type`, `@type.class`)
- Added highlighting for punctuation in type parameters, unions,
intersections, annotations, index signatures, optional fields, and
predicates (`@punctuation.special`, `@punctuation.bracket`)
- Added highlighting for identifiers in JSDoc comments
(`@variable.jsdoc`)

Release Notes:

- Refined syntax highlighting in JavaScript and TypeScript for better
visual distinction of
  types, parameters, and JSDoc elements

Release Notes:

- Fixed left click not allowing to follow in collab title bar on windows

## Summary

Follow-up to #40716. This applies the same `reset_exception_ports()` fix
to `set_pre_exec_to_start_new_session()`, which is used by shell
environment capture, terminal spawning, and DAP transport.

### Root Cause

After more debugging, I finally figured out what was causing the issue
on my machine. Here's what was happening:

1. Zed spawns a login shell (zsh) to capture environment variables
2. A pipe is created: reader in Zed, writer mapped to fd 0 in zsh
3. zsh sources `.zshrc` → loads oh-my-zsh → runs poetry plugin
4. Poetry plugin runs `poetry completions zsh &|` in background
5. Poetry inherits fd 0 (the pipe's write end) from zsh
6. zsh finishes `zed --printenv` and exits
7. Poetry still holds fd 0 open
8. Zed's `reader.read_to_end()` blocks waiting for all writers to close
9. Poetry hangs (likely due to inherited crash handler exception ports
interfering with its normal operation)
10. Pipe stays open → Zed stuck → no more processes spawn (including
LSPs)

I confirmed this by killing the hanging `poetry` process, which
immediately unblocked Zed and allowed LSPs to start. However, this
workaround was needed every time I started Zed.

While poetry was the culprit in my case, this can affect any shell
configuration that spawns background processes during initialization
(oh-my-zsh plugins, direnv, asdf, nvm, etc.).

Fixes #36754

## Test plan

- [x] Build with `ZED_GENERATE_MINIDUMPS=true` to force crash handler
initialization
- [x] Verify crash handler logs appear ("spawning crash handler
process", "crash handler registered")
- [x] Confirm LSPs start correctly with shell plugins that spawn
background processes

Release Notes:

- Fixed an issue on macOS where LSPs could fail to start when shell
plugins spawn background processes during environment capture.

This bug was caused by using two separate keys for writing/reading from
the KVP database. The bug didn't show up in my debug build because there
was an old entry of a valid key.

I added an integration test for this feature to prevent future
regressions as well.

Release Notes:

- debugger: Fix a bug where the stack frame filter state wouldn't
persist between sessions

This PR fixes that the `Current State` option inside the history
dropdown does not updating the UI. This was because we didn't send the
`SessionEvent::HistoricSnapshotSelected` event in the reset case. This
was just a mistake.

We were seeing clicks on the "View Panel" and "Dismiss" buttons
sometimes not being triggered. I believe this was happening because the
overall parent also had an on_click, which due to this being a popup
window, was causing conflicts with the buttons' on click handlers. This
should hopefully fix that issue.

would sometimes not trigger their actions.

Make gpui's `rems()`, `phi()`, `auto()` length related helpers into

I can't see why these functions aren't already const except that it

phi() and auto() whilst I was in the neighbourhood

Instead of allocating a one-element vec on the heap, we can just use an

Follow-up of https://github.com/zed-industries/zed/pull/43854
Closes https://github.com/zed-industries/zed/issues/40970

Seems that json language server does not distinguish between JSONC and
JSON files in runtime, but there is a static schema, which accepts globs
in its `fileMatch` fields.

Use all glob overrides and file suffixes for JSONC inside those match
fields, and provide a grammar for such matches, which accepts trailing
commas.

Release Notes:

- Improved JSONC trailing comma handling

Follow up to https://github.com/zed-industries/zed/pull/42819 and
https://github.com/zed-industries/zed/pull/44206.

- Make this picker feel more consistent with other similar pickers
(namely, the project picker)
- Move actions to the footer and toggle them conditionally
- Only show the "Create" and "Create New From: {default}" when we're
selecting the "Create" list item _or_ when that item is the only
visible. This means I'm changing here the state transition to only
change to `NewBranch/NewRemote` if we only have those items available.
- Reuse more UI code and use components when available (e.g.,
`ListHeader`)
- Remove secondary actions from the list item

Next step (in another PR), will be refine the same picker in the
smaller, panel version.

There's still a weird problem happening where the labels (and the label
on the tab, too, for what is worth) flicker as the file history view
gets smaller. I suspect that problem is related to something
else—potentially the truncation algorithm or focus management—so I'm not
solving it here.

- Replace `gpui::styled::Styled.font_family()` calls with
`gpui::styled::Styled.font()` when laying out inline diagnostics and

Sometimes machines are configured to drop outbound packets (rather than
reject connections). In these cases, curl/wget just hang causing our
download step to never complete. This PR adds a timeout of 10s for the
connection (not the whole download), so that in situations like this we
can fallback to our client-side download eventually.

Release Notes:

- remote: Add 10s connect timeout for server download

We have seen cases (see
https://github.com/zed-industries/zed/issues/43694) where the user's
shell initialization script includes text that ends up in the output of
the commands we use to detect the platform and shell of the remote. This
solution isn't perfect, but it should address the issue in most
situations since both commands should only output one line.

Release Notes:

- remote: Improve resiliency when initialization scripts output text

The bug was introduced in this recent PR:
https://github.com/zed-industries/zed/pull/42819. Since it's still in
nightly, there is no need for release notes.

I also polished the feature a bit by:
- Ensuring branch names are always a single line so the branch picker's
uniform list uses the correct element height.
- Adding tooltip text for the filter remotes button.
- Fixing the create branch from default icon showing up for non-new
branch entries.

The JSON language server looks for a top-level `allowTrailingCommas`
flag to decide whether it should warn for trailing commas. Since the
JSONC parser for these builtin files can handles trailing commas, adding
this flag to the schema also prevents a warning for those commas.

I don't think there's an issue that is only for this specific issue, but
it relates to *many* existing / older issues:
- #18509
- #17487
- #40970
- #18509
- #21303

Release Notes:

- Suppress warning for trailing commas in builtin JSON files
(`settings.json`, `keymap.json`, etc.)

Just recently realized we don't need this custom component for it given
we now have `Tooltip::element`. UI result is exactly the same; nothing

for a specific buffer ID following the pattern of
`disable_header_for_buffer`.
