This pull request adds a new GitHub Actions workflow to automate
reviewer assignment for pull requests. The workflow leverages the
`codeowner-coordinator` repository to intelligently assign the most
relevant teams as reviewers based on the changes in the PR. This should
streamline the review process and ensure the right teams are notified.

**Automated Reviewer Assignment Workflow:**

* Introduced `.github/workflows/assign-reviewers.yml`, a workflow that
triggers on PR open and ready-for-review events to assign 1-2 relevant
teams as reviewers using a script from the
`zed-industries/codeowner-coordinator` repository.
* The workflow checks out the coordinator repo, sets up Python, installs
dependencies, and runs the assignment script with the necessary
environment variables.
* Reviewer assignment is only performed for PRs originating from within
the organization for now.
* The output of the reviewer assignment step is maintained as an Actions
artifact for later inspection or debugging.

The "Expand All Files"/"Collapse All Files" button in `BufferSearchBar`
was broken for `SplittableEditor`, which is used in the project diff
view. It was happening because `ProjectDiff::as_searchable` returns an
handle to the `SplittableEditor`, which the search bar implementation
then tries to downcast to an `Editor`, which the `SplittableEditor` did
not support, so both the expand/collapse all buttons, as well as the
collapse state were broken.

Unfortunately this was accidentally introduced in
https://github.com/zed-industries/zed/pull/48773 , so this Pull Request
updates the `Item` implementation for `SplittableEditor` in order for it
to be able to act as an `Editor`.

Release Notes:

- Fix the "Expand All Files"/"Collapse All Files" button in the project
diff view

Fixes #50835

### Problem :
The "View AI Settings" button on the Welcome page was always rendered
regardless of the disable_ai setting. This made it visible (and
non-functional) for users who had AI disabled, which was confusing.

### Fix :
- Adds an optional visibility: Option<fn(&App) -> bool> predicate field
to SectionEntry
- At render time, Section::render uses filter_map to skip entries whose
predicate returns false.
- The "View AI Settings" entry is given a predicate that checks
!DisableAiSettings::get_global(cx).disable_ai, matching the same pattern
used in `title_bar.rs` and `quick_action_bar.rs`.
- All other entries have visibility: None, meaning they are always shown
— no behaviour change for them.

Release Notes:

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:

- N/A

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

Reuse the existing read-only bundled editor when opening default

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

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

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.
