Now, when clicking on an existing selection, the cursor will change on
`mouse_up` when `drag_and_drop_selection` is `true`. When
`drag_and_drop_selection` is `false`, it will change on `mouse_down`
(previous default).

VS Code has a behavior where it coalesces consecutive spaces in new
buffer tab titles, which I quite like. This presents the content better
and allows more meaningful content to be displayed, as consecutive
spaces don't count towards the 40 character limit.

For new, unsaved files:

- If a buffer has no content, or contains only whitespace, use
`untitled`
- If a buffer has content, take the first 40 chars of the first line

Note that this implementation also trims all leading whitespace, so that
if the buffer has any non-whitespace content, we use it. VS Code and

Closes https://github.com/zed-industries/zed/issues/32316

Multi buffer design was changed so that control buttons are not
occupying extra lines, the hardcoded logic for that is obsolete thus
removed.

Release Notes:

- Fixed incorrect offsets during outline panel navigation in singleton
buffers

This was causing a lot of work on startup, particularly due to
instantiating edit tool cards. The minor downside is that now these
threads don't open quite as fast.

Includes a few other improvements:

* On text thread rename, now immediately updates the metadata for
display in the UI instead of waiting for reload.

* On text thread rename, first renames the file before writing. Before
if the file removal failed you'd end up with a duplicate.

* Now only stores text thread file names instead of full paths. This is
more concise and allows for the app data dir changing location.

* Renames `ThreadStore::unordered_threads` to
`ThreadStore::reverse_chronological_threads` (and removes the old one
that sorted), since the recent change to use a SQL database queries them
in that order.

* Removes `ContextStore::reverse_chronological_contexts` since it was
only used in one location where it does sorting anyway - no need to sort
twice.

* `SavedContextMetadata::title` is now `SharedString` instead of
`String`.

- Fixed regression in startup performance by not deserializing and
instantiating recently opened agent threads.

The underlying `sql-formatter` used by `prettier-plugin-sql` needs to
have the SQL dialect (mysql, postgresql) passed as the prettier language
name, while Zed passes `sql`, which default will corrupt sql files with
vendor specific extensions (postgresql jsonb operators, etc).

I improved the [Zed SQL Language
Docs](https://zed.dev/docs/languages/sql) in
https://github.com/zed-industries/zed/pull/32003 to show how to use
`sql-formatter` directly as an external formatter.

Release Notes:

- SQL: Disable `format_on_save` using `prettier-plugin-sql` by default.
Please see the [Zed SQL Language
Docs](https://zed.dev/docs/languages/sql) for settings to use
`sql-formatter` directly instead.

Implements the workspace diagnostics pulling, and replaces "pull
diagnostics every open editors' buffer" strategy with "pull changed
buffer's diagnostics" + "schedule workspace diagnostics pull" for the
rest of the diagnostics.

This means that if the server does not support the workspace diagnostics
and does not return more in linked files, only the currently edited
buffer has its diagnostics updated.

This is better than the existing implementation that causes a lot of
diagnostics pulls to be done instead, and we can add more heuristics on
top later for querying more diagnostics.

Follow-up to #24797

This PR ensures some cursor styles do not change for draggable elements
during dragging. The linked PR covered this on the higher level for
draggable divs. However, e.g. the pane divider inbetween two editors is
not a draggable div and thus still has the issue that the cursor style
changes during dragging. This PR fixes this issue by setting the hitbox
to `None` in cases where the element is currently being dragged, which
ensures the cursor style is applied to the cursor no matter what during
dragging.

Namely, this change fixes this for
- non-div pane dividers
- minimap slider and the
- editor scrollbars

and implements it for the UI scrollbars (Notably, UI scrollbars do
already have `cursor_default` on their parent container but would not
keep this during dragging. I opted out on removing this from the parent
containers until #30194 or a similar PR is merged).

Closes #32205

The issue was that in some places the end of the replacement range used
anchors with `Bias::Left` instead of `Bias::Right`. Before #31872
completions were recomputed on every change and so the anchor bias
didn't matter. After that change, the end anchor didn't move as the
user's typing. Changing it to `Bias::Right` to "stick" to the character
to the right of the cursor fixes this.

The info for `max_tokens` for the model is included in

      "max_context_length": 32768
    },
```

## Notes
The response from `{api_url}/models` seems to return the `max_tokens`
for the model, not the currently configured context length, but I think
showing the `max_tokens` for the model is better than setting 2k for
everything

`loaded_context_length` exists, but only if the model is loaded at the
startup of zed, which usually isn't the case

maybe `fetch_models` should be rerun when swapping lmstudio models

### Currently configured context
this isn't shown in `{api_url}/models`

This change is used to solve the problem of not being able to respond
correctly in two-layer scrolling (in different directions). This is a
common practical requirement.

As in the example, in actual use, there may be a scene with a horizontal
scroll in a vertical scroll. Before the modification, if we scroll up
and down in the area that can scroll horizontally, it will not respond
(because it is blocked by the horizontal scroll layer).

This change may cause many side effects, causing some scrolling details
to be different from before, and more testing and analysis are needed.

I have tested some existing scenarios of Zed (such as opening the Branch
panel on the Editor and scrolling) and it seems to be correct (but it is
possible that I don’t know some interaction details). Here, the person
who added this line of code before needs to evaluate the original
purpose.

A simple way to draw dashed lines.

I didn't find an executor-agnostic watch crate that was well maintained
(we already tried postage and async-watch), so decided to implement it
our own version.

Release Notes:

- Fixed a panic that could sometimes occur when the agent performed
edits.

This changes the context server crate so that the input/output for a
request are encoded at the type level, similar to how it is done for LSP
requests.

This also makes it easier to write tests that mock context servers, e.g.
you can write something like this now when using the `test-support`
feature of the `context-server` crate:

```rust
create_fake_transport("mcp-1", cx.background_executor())
    .on_request::<context_server::types::request::PromptsList>(|_params| {
        PromptsListResponse {

Closes #27596

The problem in this case was incorrect identification of which language
(layer) contains the selection.

Language layer selection incorrectly assumed that the deepest
`SyntaxLayer` containing a range was the most specific. This worked for
Markdown (base document + injected subtrees) but failed for PHP, where
`injection.combined` injections are used to make HTML logically function
as the base layer, despite being at a greater depth in the layer stack.
This caused HTML to be incorrectly identified as the most specific
language for PHP ranges.

The solution is to track included sub-ranges for syntax layers and
filter out layers that don't contain a sub-range covering the desired
range. The top-level layer is never filtered to ensure gaps between
sibling nodes always have a fallback language, as the top-level layer is
likely more correct than the default language settings.

Release Notes:

- Fixed an issue in PHP where PHP language settings would be
occasionally overridden by HTML language settings

I can reproduce #11671 on current Nightly but not on `main`; it looks
like https://github.com/zed-industries/zed/pull/32204 fixed it. So I'm
adding a regression test and closing that issue.

Closes #11671
