This PR adjusts the "View More" button in the sidebar to expose threads
in batches of 5. Once you've expanded the whole available set, a button
to collapse the list back to the default number appears at the bottom.
Similarly, as soon as you expand the list even once, a button in the
group header shows up that does the same thing.

No release notes because this is still under feature flag.

Extract data table modules into separate files

This PR extracts the `tests` and `table_row` modules from
`data_table.rs` into separate files to improve code organization. This
is preparatory work for the upcoming column width API rework (#2 in the
series), where separating mechanical changes from logical changes will
make the review easier.

The extraction was performed using rust-analyzer's "Extract module to
file" command.

**Context:**

This is part 1 of a 3-PR series improving data table column width
handling:
1. **This PR**: Extract modules into separate files (mechanical change)
2. [#51060](https://github.com/zed-industries/zed/pull/51060) -
Introduce width config enum for redistributable column widths (API
rework)
3. Implement independently resizable column widths (new feature)

The series builds on previously merged infrastructure:
- [#46341](https://github.com/zed-industries/zed/pull/46341) - Data
table dynamic column support
- [#46190](https://github.com/zed-industries/zed/pull/46190) - Variable
row height mode for data tables

Primary beneficiary: CSV preview feature
([#48207](https://github.com/zed-industries/zed/pull/48207))

Release Notes:

Fixes ZED-517

Can be reproed by:

    Going into server options of the last server on your list.
    selecting "Remove server".
Clicking on the button AND issuing menu::Confirm action at the same time
(well, roughly the same time).

The result: OS pop-up is issued twice; if the user does confirm twice,
that's when that panic is hit.

Release Notes:

- Fixed a potential crash when deleting SSH servers too eagerly.

Add a `git::RestoreAndNext` action that restores the diff hunk at the
cursor and advances to the next hunk. In the git diff view, the default
restore keybinding (`cmd-alt-z` on macOS, `ctrl-k ctrl-r` on
Linux/Windows) is remapped to this action so users can quickly restore
hunks in sequence. Also refactor `go_to_hunk_before_or_after_position`
to accept a `wrap_around` parameter, eliminating duplicated
hunk-navigation logic in `do_stage_or_unstage_and_next` and
`restore_and_next`.

Release Notes:

- Added a `git: restore and next` action that restores the diff hunk at
  the cursor and moves to the next one. In the git diff view, the
  default restore keybinding (`cmd-alt-z` on macOS, `ctrl-k ctrl-r` on
  Linux/Windows) now triggers this action instead of `git: restore`.

In `BlockMap::sync`, blocks within an edited region are sorted and
processed sequentially. Each block placement computes
`rows_before_block` by subtracting `new_transforms.summary().input_rows`
from the block's target position. The `Near`/`Below` cases have a guard
that skips the block if the target is already behind the current
progress, but `Above` and `Replace` were missing this guard.

When a `Replace` block (tie_break 0) is processed before an `Above`
block (tie_break 1) at the same or overlapping position, the `Replace`
block consumes multiple input rows, advancing `input_rows` past the
`Above` block's position. The subsequent `position - input_rows`
subtraction underflows on `u32`, producing a huge `RowDelta` that wraps
`wrap_row_end` past `wrap_row_start`, creating an inverted range that
propagates through the display map layers and panics as `begin <= end
(47 <= 0)` in a rope chunk slice.

Add underflow guards to `Above` and `Replace`, matching the existing
pattern in `Near`/`Below`.

Release Notes:

- Fixed a source of underflowing subtractions causing spurious panics

Fixes ZED-5M9

No test as I couldn't quite reproduce this, as the cause is mostly a
guess

Release Notes:

Closes #46837

Reuse the existing read-only bundled editor when opening default
settings or default key bindings again, instead of creating a duplicate
tab each time.

The title in the YAML front matter contained a colon, which YAML

Previously, `get_layer_surface` always passed `None` as the output,

output regardless of the requested display.

Fixes #42444

- Changed `accepts_text_input` on the editor to be more precise.
Previously, it returned `true` only in insert mode. Now it also returns
`true` when an operator is pending.
- On Windows, we disable the IME whenever there is no input handler
which `accepts_text_input`.
- How this improves Vim mode: in insert mode, the IME is enabled; in
normal mode, it is disabled (command keys are not intercepted); when an
operator is pending, the IME is re-enabled.

Release Notes:

- On Windows, the IME is disabled in Vim normal and visual modes.

On Windows, the WSL VM always boots up when Zed is opened, because we
eagerly discover which jupyter kernels are installed inside WSL on
startup. This is not desirable if the REPL feature is not being used.
Defer this work to the point where we actually need to know what kernels
are installed.

Release Notes:

(This should be merged after #48332)

This PR exposes the LSP settings schema functionality to extensions,
allowing them to provide JSON schema for `initialization_options` and
`settings` fields to enable autocomplete in settings files.

New extension API methods (v0.8.0+):
- `language_server_initialization_options_schema`
- `language_server_settings_schema`

Both methods return an optional JSON string conforming to JSON schema.
Older extension versions gracefully return `None`.

Release Notes:

- Added support for settings schemas for the next version of the
extension API so that settings autocompletion can be provided for
language server settings.

Updates #50970

While investigating the executor shutdown code, Claude noticed that we
never
actually drop the app because of a reference cycle.

Release Notes:

- N/A

Co-Authored-By: Eric Holk <eric@zed.dev>

In app drop we had been calling `.close()` on the executors. This caused
problems with the BackgroundExecutor on Linux because it raced with
concurrent work: If task A was running and about to poll task B, the
poll to task B would panic with "Task polled after completion". This
didn't really matter (because the app was shutting down anyway) but
inflated our panic metrics on Linux.

It turns out that the call to `.close()` is not needed. It was added to
prevent foreground tasks being scheduled after the app was dropped; but
on all platforms the App run method does not return until after the
ForegroundExecutor is stopped (so no further tasks will run anyway).

The background case is more interesting. In test code it didn't matter
(the background executor is simulated on the main thread so tests can't
leak tasks); in app code it also didn't really make a difference. When
`fn main` returns (which it does immediately after the app is dropped)
all the background threads will be cancelled anyway.

Further confounding debugging, it turns out that the App does not get
dropped on macOS and Windows due to a reference cycle; so this was only
happening on Linux where the app quit callback is dropped instead of
retained after being called. (Fix in #50985)

When checking a box in the markdown preview, it's generally very slow.

Preview updates when typing in the editor are debounced to be every
200ms, but when clicking an element in the preview, it feels sluggish to
wait that long.

In debugging, I found that the debounced task from the editor event
subscriptions replaced the non-debounced event on [line
605](https://github.com/zed-industries/zed/blob/263d8e58d809b493044160cb26fb690169007e4e/crates/markdown_preview/src/markdown_preview_view.rs#L600C49-L602C51),
and the UI took around 200 ms to update.

Therefore, I've changed the markdown parsing function to not replace the
task, unless another non-debounced task comes along. UI updates from the
editor are still debounced.

Closes #46846

When `disable_ai: true` is set in user settings, Zed was still
connecting to configured MCP (context) servers and sending
initialization requests. This change adds checks for `DisableAiSettings`
in `ContextServerStore` to:

- Skip server connections when AI is disabled
- Disconnect from running servers when AI becomes disabled
- Connect to servers when AI is re-enabled
- Prevent registry changes from triggering connections while AI is
disabled

The fix tracks `ai_disabled` state to detect transitions and properly
manage server connections when AI is toggled.

Release Notes:

- Fixed Zed connecting to MCP servers when AI is disabled.
