`BufferId` can change between file reopens: e.g. open the buffer, close
it, go back in history to reopen it — the 2nd one will have a different
`BufferId`, but the same `result_ids` semantically.

The dock size for the git panel wasn't being persisted across Zed
restarts. This was because the git panel lacked the serialization
pattern used by other panels.

When using Deno with the example configuration as described here,
duplicate lsp information is displayed in Javascript files.

This pull request solves that issue by adding Javascript to the
configuration.

Release Notes:

- Improve LSP support when using Deno with Javascript using the default
configuration.

First of all thank you for such a fast editor!

I realized that the existing support for detecting runnable test cases
for typescript/javascript is not full. Meanwhile I can run most of test
by pressing "run button":

I was curious whether I can improve it on my own and created this pr. I
edited schemas and added minor changes in `TaskTemplate` to allow to
replace '%s' with regexp pattern, so it can match test cases:

Update the `vim::normal::search::Vim.search` method in order to
correctly set the search bar's case sensitive search option if the
`search.case_sensitive` setting is enabled.

Closes #32172 

Release Notes:

- vim: Fixed a bug where the `search.case_sensitive` setting was not respected when activating search with <kbd>/</kbd> (`vim::Search`)

Tested with following models. Hallucinates with whites outline images
like white lined zed logo but works fine with zed black outlined logo:

Pixtral 12B (pixtral-12b-latest)
Pixtral Large (pixtral-large-latest)
Mistral Medium (mistral-medium-latest)
Mistral Small (mistral-small-latest)

After this PR, almost all of the zed's llm provider who support images
are now supported. Only remaining one is LMStudio. Hopefully we will get
that one as well soon.

Release Notes:

- Add support for images to mistral models

It works similar to how deepseek works where the thinking is returned as
reasoning_content and we don't have to send the reasoning_content back
in the request.

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

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`.

Release Notes:

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

Recently in this PR: https://github.com/zed-industries/zed/pull/32248
github copilot settings was introduced. This had missing settings update
which was leading to github copilot models not getting fetched. This had
missing subscription to update the settings inside the copilot language
model provider. Which caused it not show models at all.

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.

Follow-up of https://github.com/zed-industries/zed/pull/19230

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.
