This PR makes the loading state clearer by disabling the message editor
while the agent is loading as well as pulsating the icon.

Release Notes:

- agent: Made the thread loading state clearer in the agent panel.

This PR uses view transition animations to reduce the page flickering
when navigating between one and the other. Pretty cool CSS-only
solution.

Note that the truncation strategy on the file path is not yet perfect.
I'm just applying the regular method from the label component, but we
should wrap path text from the start rather than from the end. Some time
in the future!

Release Notes:

- Fixed a bug where the "Open File" button would overflow in the
multibuffer header if the file path was too long.

Closes https://github.com/zed-industries/zed/issues/43728

Release Notes:

- agent: Fixed a bug where the plan and edit files list would consume
the whole space of the thread if they were too long. They're now capped
by a max-height and scrollable.

This is still not perfect, but it reduces the shift that happens when
navigating between pages that have and don't have the table of contents.
It also tries to reduce the theme flicker that happens by moving its
loading to an earlier moment.

Release Notes:

- N/A

Adds clarifying examples and information about the `include_pattern`
parameter for the grep tool, analogous to the `path` parameter of the
read and list tools and others.

The lack of clarity led to unexpected agent behavior described in
#41189. This change is confirmed to improve the precision of Claude
Sonnet 4.5 when searching for code in an empty conversation (without it,
it leaves out the root directory in the query).

Closes #41189.

```
Release Notes:

- Clarify grep tool description to improve agent precision when using it with the `include_pattern` parameter
```

Closes #43040

Release Notes:

- Remove the end-of-support Gemini 1.5 model from the options.
- Remove the older Gemini 2.0 model from the options.
- Please let me know if you think it's better to keep it, as it is still
a usable model.
- Update the incorrect amounts for some input/output tokens.
- Update the default model to Gemini 2.5 Flash-Lite.
- Rename variant `Gemini3ProPreview` to `Gemini3Pro`

When this PR is merged, users will be able to select the following
Gemini models.

- 2.5 Flash
- 2.5 Flash-Lite
- 2.5 Pro
- 3 Pro

This PR adds the ability to collapse section in the docs sidebar (which
are persistent until you close the tab), and some design facelift to the
docs, which makes its design close to the site as well as polishing up
many elements and interactions (like moving the search to a modal and
making the table of content visible in smaller breakpoints).

Release Notes:

- Added a keybinding to open the `settings.json` file when the Settings
UI is in focus: `cmd-,` (macOS) / `ctrl-,` (Windows / Linux).
- A tooltip was added to the `Edit in settings.json` button to show this
keybinding.

- shorten some phrases to (hopefully) retain attention better
- move the required field up to not bore people with scrolling
- call it a bug and not an issue to further emphasize we want feature
requests in Discussions where the product managers are
- remove the default from the WSL question since not everyone does
WSL or even Windows

There is still room for improvement here as `anchor(s)_in_excerpt` is
generally a bad API here due to it reseeking the entire excerpt tree
from the start on every call which we don't really need. But this at
least cuts the seeks down by a factor of 4 for now.

Release Notes:

- Improved performance of bracket colorization in large multibuffers

Introduces new "mapping point cursors" for the different display map
layers allowing one to map multiple points in increasing order more
efficiently than using the one shot operations.

This is used in the `BlockMap::sync` for `header_and_footer_blocks`
which spends a significant time in sumtree traversal due to repeatedly
transforming points between the different layers. This effectively turns
the complexity of those operations from quadratic in the number of
excerpts to linear, as we only go through the respective sumtrees once
instead of restarting from the start over and over again.

Release Notes:

- Improved performance for editors of large multibuffers with many
different files

These are long running foreground tasks that tend to not have pending
await points, meaning once we start executing them they will never
reschedule themselves, starving the foreground thread.

Release Notes:

- Improved git project diff responsiveness

Replace single quotes with double quotes when referencing the askpass
script name in the helper command. The Windows command processor
(cmd.exe) requires double quotes for proper string handling, as single
quotes are treated as literal characters.

Error I get when trying to open remote project:

This change modifies the color assignment for phantom elements in the
editor. If a phantom element collides with existing elements, it now
uses a custom color based on the theme's debugger accent with reduced
opacity. Otherwise, it defaults to the hint color.

Without this new flag, the Sweep API will actually produce a combination

We restructured `struct Repository` a bit so that it now stores a shared
task of `enum RepositoryState`. This way, we can now re-use it outside
of the git job queue when spawning a git job a standalone bg task. An
example here would be `git-blame` that does not require any file locks
and is not susceptible to git job ordering.

As a result of this change, loading (and modifying) a file that contains
a huge git history will no longer block other git operations on the repo
such as staging/unstaging/committing.

Release Notes:

- Improved overall git experience when loading buffers with massive git
history where they would block other git jobs from running (such as
staging/unstaging/commiting). Now, git-blame will run separately from
the git job queue on the side and the buffer with blame hints when
finished thus unblocking other git operations.

Sometimes we are unable to receive messages at all from an agent. This
puts on upper bound on the `initialize` call so we can at least give a
message to the user that something is wrong here.

30s might feel like too long, but I wanted to avoid some false positives
in case there was something an agent needed to do at startup. This will
still communicate to the user at some point that something is wrong,
rather than leave them waiting forever with no signal that something is
going wrong.

Release Notes:

- agent: Show an error message to the user if we are unable to
initialize an ACP agent in a reasonable amount of time.

Update the way that both
`search::buffer_search::BufferSearchBar.replace_next` and
`search::buffer_search::BufferSearchBar.replace_all` are registered as
listeners, so that we don't require the replacement editor to be focused
in order for these listeners to be active, only requiring the
replacement mode to be active in the buffer search bar.

This means that, even if the user is focused on the buffer editor, if
the "Replace Next Match" or "Replace All Matches" buttons are clicked,
the replacement will be performed.

Closes #42471 

Release Notes:

- Fixed issue with buffer search bar where the replacement buttons
("Replace Next Match" & "Replace All Matches") wouldn't work if search
bar was not focused

Fixes ZED-3P9

We only clamped the end which for a completely wrong input could cause
us to construct a reversed range which will end up underflowing later

Zeta evals now include a character n-gram metric adapted for multi-edit diffs (“delta chrF”). It works as follows:

1. Reconstruct the original, golden (expected), and actual texts from unified diffs.
   - "original": the text before any edits
   - "golden": the text after applying the expected edits
   - "actual": the text after applying the actual edits

2. Compute n-gram count deltas between original→golden and original→actual.
   - n-grams are computed as in chrF (max n=6, whitespace ignored).

3. Compare these deltas to assess how well the actual edits match the expected edits.
   - As in standard chrF, classify n-grams as true positives, false positives, and false negatives, and report the F-beta score with beta=2.

Current approach is to colorize brackets based on their depth, which was
broken for markdown:

<img width="388" height="50" alt="image"
src="https://github.com/user-attachments/assets/bd8b6c2f-5a26-4d6b-a301-88675bf05920"
/>

Markdown grammar, for bracket queries
https://github.com/zed-industries/zed/blob/00e93bfa113a3daed6e4a97a7244ad04d58453ee/crates/languages/src/markdown/brackets.scm#L1-L8

and markdown document `[LLM-powered features](./ai/overview.md), [bring
and configure your own API
keys](./ai/llm-providers.md#use-your-own-keys)`, matches first bracket
(offset 0) with two different ones:

* `[LLM-powered features]`

* `[LLM-powered features](./ai/overview.md), [bring and configure your
own API keys]`

which mix and add different color markers.

Now, in case multiple pairs exist for the same first bracket, Zed will
only colorize the shortest one:

Release Notes:

- Fixed bracket colorization mixing colors in markdown files

Release Notes:

- Fixed a small issue where bracket colors would not be immediately
updated if `experimental_theme_overrides.accents` was changed.
