Instead of allocating a one-element vec on the heap, we can just use an
array here (since `Editor::edit` accepts anything that implements
`IntoIterator`).

I haven't checked if there are more instances that can be simplified,
just accidentally stumbled upon this when working on something else in
the markdown preview crate.

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

- 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

`editor::hover_popover::diagnostics_markdown_style` to ensure that
both the UI and Buffer font features are used in both markdown and
diagnostics popover.

Closes #44209 

Release Notes:

- Fixed font feature application for inline git blame, inline
diagnostics, markdown popovers and diagnostics popovers

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.

Related to but doesn't fully fix:
https://github.com/zed-industries/zed/issues/43694 and
https://github.com/zed-industries/zed/issues/43718

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

Follow up to https://github.com/zed-industries/zed/pull/44162 where my
strategy for not displaying the indent guides only in the commit message
was wrong given I ended up... disabling indent guides for all the
buffers. This PR adds a new method to the editor where we can disable it
for a specific buffer ID following the pattern of
`disable_header_for_buffer`.

Closes #40757

## Summary

This PR addresses an issue where Zed incorrectly adjusts the indentation
of Markdown lists when inserting text using multiple cursors. Currently:

- Editing individual lines with a single cursor behaves correctly (no
unwanted indentation changes).
- Using multiple cursors, Zed automatically adjusts the indentation,
unlike VS Code, which preserves the existing formatting.

## Tasks
- [x] Implement a new test to verify correct Markdown indentation
behavior with multiple cursors.
- [x] Apply the fix to prevent Zed from adjusting indentation when
inserting text on multiple cursors.

------------------------

Release Notes:

- Fixed an issue where inserting text with multiple cursors inside a
nested Markdown list would cause it to lose its indentation.

Fixes a deadlock in the background scanner that occurs on single-core
Linux devices. This happens because the background scanner would `block`
on a background thread waiting for a future, but on single-core Linux
devices there would be no other thread to pick it up. This mostly
affects SSH remoting use cases where it's common for servers to have 1
vCPU.

In project search UI code we were seeing an issue where "Go to next
match" would act up and behave weirdly. It would not wrap at times.
Stuff would be weird, yo. It turned out that match ranges reported by
core project search were sometimes out of sync with the state of the
multi-buffer. As in, the sort order of
`search::ProjectSearch::match_ranges` would not match up with
multi-buffer's sort order. This is ~because multi-buffers maintain their
own sort order.

What happened within project search is that we were skipping straight
from stage 1 (filtering paths) to stage 3 via an internal channel and in
the process we've dropped the channel used to maintain result sorting.
This made is so that, given 2 files to scan:
- project/file1.rs <- not open, has to go through stage2 (FS scan)
- project/file2.rs <- open, goes straight from stage1 (path filtering)
  to stage3 (finding all matches) We would report matches for
  project/file2.rs first, because we would notice that there's an
  existing language::Buffer for it. However, we should wait for
  project/file1.rs status to be reported first before we kick off
  project/file2.rs

The fix is to use the sorting channel instead of an internal one, as
that keeps the sorting worker "in the loop" about the state of the
world.

Closes #43672

Release Notes:

- Fixed "Select next match" in project search results misbehaving when
some of the buffers within the search results were open before search
was ran.
- Fixed project search results being scrolled to the last file active
prior to running the search.

In the Linux dispatcher, we create one background thread per CPU, but
when a single core is available, having a single background thread
significantly hinders the perceived performance of Zed. This is
particularly helpful when SSH remoting to low-resource servers.

We may want to bump this to more than two threads actually, but I wanted
to be conservative, and this seems to make a big difference already.

Adds `com.apple.security.files.user-selected.read-write` and
`com.apple.security.files.downloads.read-write` to zed.entitlements.

This resolves an issue where the integrated terminal could not access

`WorkItemPriority::High` will enqueue the work items to threads with

Fancy regex has a max backtracking limit which defaults to 1,000,000
backtracks. This avoids spinning the CPU forever in the case that a
match is taking a long time (though does mean that some matches may be
missed).

Unfortunately the verison we depended on causes an infinite loop when
the backtracking limit is hit
(https://github.com/fancy-regex/fancy-regex/issues/137), so we got the
worse of both worlds: matches were missed *and* we spun the CPU forever.

Updating fixes this.

Excitingly regex may gain support for lookarounds
(https://github.com/rust-lang/regex/pull/1315), which will make
fancy-regex much less load bearing.

Closes #43821

Release Notes:

- Fix a bug where search regexes with look-around or backreferences
could hang
  the CPU. They will now abort after a certain number of match attempts.

When adding the File History option here, I used the pattern to hide the
option, since that's what another option was already doing here, but I
see other menus in the git panel (`...`) that use disabling over hiding,
which is what I think is a nicer experience (allows you to learn of
actions, the full range of actions is always visible, don't have to
worry about how multiple hidden items might interact in various
configurations, etc).

/>


In general, I think it would be good to move to being more consistent
with disabling over hiding - there are other places in the app that are
hiding - some might be valid, but others might just choices made on a
whim.

Closes #43171

Previously the tab switcher only subscribed to events from a single pane
so closing tabs in other panes wouldn't cause the tab switcher to
update. This PR changes that so the tab switcher subscribes to the whole
workspace and thus updates when tabs in other panes are closed.

It also modifies the work in #44006 to sync selected index across the
whole workspace instead of just the original pane in the case of the
all-panes tab switcher.

Release Notes:

- Fixed all-panes tab switcher not updating in response to changes in
other panes
