**Problem addressed:**

Cannot distinguish an identical path on multiple remote hosts in the
"Recent Projects" picker.

**Related work:**

- Issue #40358 (already closed) identified the issue in the "Expected
Behavior" section for both WSL and SSH remotes.
- PR #40375 implemented WSL distro labels.

**Implementation notes:**

RemoteConnectionOptions::display_name() will be subject to
exhaustiveness checking on RemoteConnectionOption variants.

Keeps the same UI approach as the WSL distro variants.

When installing local "dev" extensions that provide tree-sitter
grammars, compiling the parser can be quite intensive[^anecdote]. This
PR changes the logic to only compile the parser if the WASM object
doesn't exist or the source files are newer than the object (just like
`make(1)` would do).

[^anecdote]: The tree-sitter parser for LLVM IR takes >10 minutes to
compile and uses 20 GB of memory on my laptop.

## Summary

1. Split editor references to avoid borrow conflicts in event handlers
2. Check
[has_mouse_context_menu()](vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html)
state directly in tooltip conditional instead of caching stale value
3. Restructured context menu deployment to ensure proper sequencing:
hide popover → build menu → deploy menu → notify for re-render

This PR removes the default, error, warning, and success color variants
from the `SwitchColor` enum. In the most YAGNI spirit, I think we'll
probably never want to use these colors for the switch, so there's no
reason to support them. And if we ever want to do it, we can re-add
them.

I also took the opportunity to change the default color to be "accent",
which is _already_ what we use for all instances of this component, so
there's no need to have to define it every time. This effectively makes
the enum support only "accent" and "custom", which I think is okay for
now if we ever need an escape hatch before committing to supporting new
values.

This PR partially implements a knowledge distillation data pipeline.

`zeta distill` gets a dataset of chronologically ordered commits and
generates synthetic predictions with a teacher model (one-shot Claude
Sonnet).

`zeta distill --batches cache.db` will enable Message Batches API. Under
the first run, this command will collect all LLM requests and upload a
batch of them to Anthropic. On subsequent runs, it will check the batch
status. If ready, it will download the result and put them into the
local cache.

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.

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

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.
