the actual name of the theme, and also to maintain parity with Zed1.

We were mistakenly pushing an opaque layer without intersecting it with
the content mask. Also, we were pushing two opaque layers for the same
div unnecessarily.

This pull request also allows turning an `ArenaBox` into an `ArenaRef`
when non-mutable access is required, which makes `ArenaRef: Clone`. This
fixes a bug that prevented the command palette from reading all the
available actions while the `command_palette::Toggle` action was being
dispatched.

The feedback modal still needs a styling update

This prevents the `cmd-k` keystroke, which clears the terminal, from
staying around as a pending keystroke on the parent workspace.

Rather than relying on the focused element, instead explicitly pass the
focus handle for the query editor when determining the prev/next
bindings. Only compute these values once.

Once a drag starts, we won't fire click listeners or style any elements
as active.

- Don't fire click listeners or show active state once a drag is in
progress
- Don't show hover style when a drag is in progress
- Draw borders above content
- If borders are opaque, apply them to the content mask. This prevents
hovers from firing on content underneath the border, which was creating
issues where the drag handle was inside the border, so we'd flicker the
hover when the mouse moved out of the drag handle and into the 1px
border on the left dock.
- Add a `block_mouse` helper which causes transparent elements to paint
an "opaque" layer to prevent mouse events from falling through. We use
this for the drag handle as well to disable hover, click, etc on items
in the panel.

Release Notes:

- N/A

* Ensure that views' on_release callbacks are always called (even if
their window is gone), by passing them a `AppContext`, not a
`WindowContext`.
* Fix leaked handles to `CollabPanel`, `NotificationPanel`, and
`ChatPanel` caused by captures in a `ListState` render callback.

This fixes two issues we were seeing with following:
* inability to rejoin a remote project after you closed it
* following not working if a window had previously been closed

Now file finder will match all gitignored worktree entries.
Zed does not traverse gitignored dirs by default, which means that not
all gitignored files will be matches, but all that were toggled in
project panel and all root non-directory gitignored entries will be now
used, hopefully causing less questions.

Release Notes:

- Improved file finder to match all gitignored files that were added
into worktrees (e.g. due to opening gitignored directories in project
panel)
