This PR adds the ability to open the extensions view via the `zed:
extensions` action with a pre-selected filter.

The "Install Themes" and "Install Icon Themes" buttons in their
respective selectors take advantage of this to set the filter when
opening the view:

This PR reworks the `FakeGitRepository` type that we use for testing git
interactions, to make it more realistic. In particular, the `status`
method now derives the Git status from the differences between HEAD, the
index, and the working copy. This way, if you modify a file in the
`FakeFs`, the Git repository's `status` method will reflect that
modification.

Anthropic API doesn't allow `tool_use` messages without a corresponding
`tool_result`, so we'll skip those when building a request. I'll
separately investigate why we are sending request before the tool result
as that might lead to separate issues, but that might take a while and
this is currently very frustrating.

Reverts zed-industries/zed#27064

Closes #26847

Release Notes:

- Updated Git panel background to use panel_background instead of
ElevationIndex::Surface.bg(cx) for consistency with other panels.
- Removed redundant GitStatusColors struct from status.rs and refactored
to use existing theme colors.
- Adjusted Color enum mappings in color.rs to reference
version_control_* colors instead of status() for better alignment with
the theme system.
- Cleaned up unused or redundant code.

When you press the "Expand Excerpt Down" button, the editor will scroll
up by the same amount to keep the button in same place. This allows you
to expand the excerpt rapidly without moving your mouse.

Ensuring that text between the "you" messages align with text in the
assistant response. This also creates a nice subtle hierarchy effect
where the "you" message card is wider than the message, making it
slightly easier to tell them apart.

Sometimes the model produces SEARCH queries that don't match the
indentation of the source file exactly.

When we can't find an exact match, we'll now attempt to match the lines
while being more flexible about the leading whitespace as long as all
lines are consistently offset from the source, and extend the leading
whitespace in the REPLACE string accordingly.

cc @Anthony-Eid. One thing I noticed while doing this is that we do an

This pull request does two things:

1. Adds a setting to force Zed to use the built-in prompts, instead of
the system provided ones. I've personally found the system prompts on
macOS often fail to respond to keyboard input, are slow to render
initially, and don't match Zed's style.
2. Makes the previously Linux-only Zed provided prompts available to
everybody using the above setting.

Release Notes:
- Added support for a built-in prompting system, regardless of platform.
Use the new `use_system_prompts` setting to control whether to use the
system provided prompts or Zed's built-in system. Note that on Linux,
this setting has no effect, as Linux doesn't have a system prompting
mechanism.

TODO:
- [x] Use AsyncFn instead of Fn() -> Future in GPUI spawn methods
- [x] Implement it in the whole app
- [x] Implement it in the debugger 
- [x] Glance at the RPC crate, and see if those box future methods can
be switched over. Answer: It can't directly, as you can't make an
AsyncFn* into a trait object. There's ways around that, but they're all
more complex than just keeping the code as is.
- [ ] Fix platform specific code

By default stdenv strips all unused rpaths, but we use a few libraries
that are `dlopen`'d so we need to stop it from removing those. The
[`dontPatchELF`
flag](https://ryantm.github.io/nixpkgs/stdenv/stdenv/#var-stdenv-dontPatchELF)
disables that and makes the nix build work on wayland again.

Release Notes:

- Improved performance when using the scroll wheel and some other mouse
interactions.

Based on some cache details about GPUI `AnyView::cached` that I found in
the discussion of
https://github.com/zed-industries/zed/discussions/24260#discussioncomment-12135749,
and combined with the optimization points found in actual applications.

This change may have some scenarios that I have not considered, so I
just make a draft to put forward my ideas first for discussion.

From my analysis, `AnyView::cached` will always invalid by Div's mouse
events, because of it called `window.refresh`. I understand that (mouse
move event) this is because the interface changes related to hover and
mouse_move will be affected style, so `window.refresh` is required.
Since Div does not have the `entity_id` of View, it is impossible to
know which View should be refreshed, so the entire window can only be
refreshed.

With this change, we can reduce a lot of `render` method calls on
ScrollWheel or Mouse Event.

Tried adding a custom debugging tasks to discover two more required
properties missing from the docs.

Follow-up of https://github.com/zed-industries/zed/pull/26574/files

After that PR, settings.json stopped giving completions when `"` was
typed as a key:

https://github.com/user-attachments/assets/5ff03863-024c-4c28-a7cd-8ef48a1695d8

This goes down to 


https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/language/src/language.rs#L1736-L1748

which was empty before the PR, hence leading to lower `true` branch.
Now, when typing `"`, there's no scope according to 


https://github.com/zed-industries/zed/blob/fb12863999e601c4ffc9afbded036e4f1f064369/crates/project/src/lsp_store.rs#L4529-L4532

return result.

Removing `json-language-server` from `scope_opt_in_language_servers`
seems to preserve the `:` fix and restore the completions behavior.

It looks like:

- https://github.com/zed-industries/zed/pull/26780

accidentally added a new event type, `AssistantThreadFeedback`, using
the old event system, that it didn't end up actually using, as the code

Stalebot has a maximum operations-per-run which is set at 1000. As a

There apparently is some amdgpu/radv bug that rendering with
multisample anti-aliasing (MSAA) results in a crash when the bounds
of a triangle list exceed 1024px, which in Zed happens with the default
buffer font size when you select a line with more than 144 characters.

This crash has been reported as #26143.

This commit introduces a workaround: you can set the
ZED_PATH_SAMPLE_COUNT=0
environment variable to disable MSAA and the error message we print
when a GPU crash is encountered with radv now suggests trying this
environment
variable as a workaround and links the respective issue.

Sidenote: MSAA was introduced in
f08b1d78ec1655a56b07c5efcd74d225d2a4b7d5
so you didn't run into this driver bug with versions < 0.173.8.

Release Notes:

- Added a workaround for an AMD Linux driver bug that causes Zed to
crash when selecting long lines.

We used to fail when this happened, but we saw the model use it as a way
to create empty files, which makes sense.
