Fix Helix `o`/`O` behavior when a selection is active.

This updates `InsertLineAbove` and `InsertLineBelow` to use the
selection bounds correctly for Helix selections, including line
selections whose end is represented at column 0 of the following line.

It also adds Helix select-mode keybindings for `o` and `O`, and adds
tests covering both line selections and selections created via `v`.

Closes #43210

Release Notes:

- helix: Fixed insert line above/below behavior when a full line is
selected

## Context

This makes zed-agent prioritize rules files in the same order as is
described in the docs. My order of experience was
- saw in my zed agent thread `Using project "CLAUDE.md" file.
- went to settings to see if I can make it use `AGENTS.md` instead.
- went to [the docs](https://zed.dev/docs/ai/rules) where it specifies
that AGENTS.md is be picked over CLAUDE.md.
- went to source to see what went wrong

## How to Review

I'm changing the order of filenames in an array - the only two places
where the order matters is when picking which rules file to use. The
last place it's used with an `.iter().any()`.

## Context

This PR fixes a UX issue ("visual bug") in the collaboration panel
documented in issue
[#51800](https://github.com/zed-industries/zed/issues/51800), where
users who had already signed in were still seeing the "Sign In" screen
after restarting the editor. As I mentioned in my response there ([Link
to comment
#4132366441](https://github.com/zed-industries/zed/issues/51800#issuecomment-4132366441)),
I have investigated the problem thoroughly and found that the session is
not actually lost.

What I discovered is that in Zed, only "staff" users automatically
connect to the collaboration servers when opening the editor (by design,
this logic is in `crates/client/src/client.rs` starting at line `962`).
Therefore, regular users keep their saved session and `Authenticated`
status, but since they don't automatically connect upon startup, the UI
didn't detect this correctly. It erroneously showed the GitHub account
request and the "Sign in to enable collaboration" text, giving the false
impression that the user had been logged out.

### Screenshots

/>


**Note:** This PR specifically addresses the visual issue in the
**Collab Panel**. Similar behaviors might exist in other parts of the
editor, but this change focuses on correcting the collaboration
interface.

This current PR:
1. Improves the `render_signed_out` function in
`crates/collab_ui/src/collab_panel.rs`.
2. Simplifies the connection check using
`self.client.user_id().is_some()`, which is more robust against volatile
network states and perfectly covers connection transitions.
3. During rendering, it detects existing credentials and shows the
correct message "Connect" / "Connecting...", replacing the GitHub icon
with the appropriate network icon (`SignalHigh`).

## How to Review

- Review the cleaner and simplified code in
`crates/collab_ui/src/collab_panel.rs:render_signed_out`.
- Verify that instead of verbose validations on the `Status` enum,
simply checking the user ID correctly captures any subsequent subtype,
properly differentiating between account authorization and a simple
network reconnection.

Release Notes:

- Fixed an issue (#51800) in the Collab Panel where the UI appeared to
log users out. Implemented improvements to properly differentiate
between "Sign In" and "Connect," avoiding false authentication prompts
when users are already logged in but not automatically connected to the
servers.

Ever since we introduced the agent panel the way it is right now back in
May 2025, we wanted to make the thread generation be top-down. Now, with
the changes we're planning to launch very soon revolving around parallel
agents, doing this become even more important for a better experience.
Particularly because in the agent panel's new empty state, the message
editor is full screen. We want to minimize as much as possible layout
shift between writing your first prompt and actually submitting it. So
this means that content will stream down from your first prompt and
auto-scroll you if it goes beyond the viewport.

To pull this off, we added a `follow_tail` feature directly to the GPUI
list so that we could only call it in the thread view layer as opposed
to doing it all there.

Release Notes:

- Agent: Made the thread generation be top-down instead of bottom-up.
Agent content now streams from the top and auto-scroll as they go beyond
the viewport.

Release Notes:

- Fixed an issue where some settings used the wrong documentation in LSP hover documentation

LSP's `CompletionItemKind` is defined by the protocol and may not have a
corresponding highlight name in a language's `highlights.scm`. For
example, Julia's grammar defines `@function.call` but not `@function`,
so completions with `Method` kind cannot resolve a highlight. Since the
mapping from `CompletionItemKind` to highlight names is an internal
implementation detail that is not guaranteed to be stable, the fallback
behavior should provide consistent styling regardless of grammar
definitions.

Bundled language extensions (e.g., Rust, TypeScript) apply `fade_out` or
muted styling to the description portion of completion labels, so the
fallback path and extension-provided labels should match this behavior.

Previously, the description portion could fail to receive the expected
`fade_out` styling in several independent cases:

1. When `runs` was empty (grammar lacks the highlight name), the
`flat_map` loop never executed
2. When theme lacked a style for the `highlight_id`, early return
skipped the `fade_out` logic
3. When extensions used `Literal` spans with `highlight_name: None`,
`HighlightId::default()` was still added to `runs`, preventing
`fade_out` from being applied

The fix ensures description portions consistently receive `fade_out`
styling regardless of whether the label portion can be highlighted, both
for fallback completions and extension-provided labels.

The workflow run at
https://github.com/zed-industries/zed/actions/runs/23557683707 succeeded
but threw some warnings for a rather-soon Node.js 20 deprecation (June
2nd).

Hence, this PR updates in that context mentioned workflows to newer
versions from which on the actions will use Node.js 24.

Namely, this updates
- `actions/checkout`
- `actions/create-github-app-token` and
- `peter-evans/create-pull-request`

to their latest version which includes said updates. As for their most
recent versions, all of these actions just updated their versions to
account for said deprecation.

We now use the parser and renderer from the `markdown` crate for
Markdown Preview, instead of maintaining two separate code paths.

How it works:

`markdown_preview_view.rs` is now a consumer of `MarkdownElement`. It
acts as a thin wrapper, handling things like resolving URL clicks and
image URLs, which can vary between consumers. It also handles syncing
the editor selection with the active block in the preview. The APIs for
this are provided by `MarkdownElement`.

All the heavy lifting like parsing HTML, rendering block markers on
hover, handling the active block, etc. is done by `MarkdownElement`.
Everything is opt-in. For example, markdown in the Agent Panel can
choose not to enable block marker rendering or HTML parsing, while
Markdown Preview opts into those features.

Final outcome:

For Markdown Preview View:

- Added:
  - Selection support in the preview

- Stays:
  - Syncing between editor and preview
  - Autoscroll
  - Hover and active block markers
  - Checkbox toggling
  - Image rendering
  - Mermaid rendering

For the `markdown` crate:

- No changes for existing consumers like the Agent Panel
- Consumers can now opt into:
  - HTML rendering
  - Block marker rendering
  - Click event handling
  - Custom image resolvers
  - Mermaid rendering

This extracts a `language_core` crate from the existing `language`
crate, and creates a `grammars` data crate. The goal is to separate
tree-sitter grammar infrastructure, language configuration, and LSP
adapter types from the heavier buffer/editor integration layer in
`language`.

## Motivation

The `language` crate pulls in `text`, `theme`, `settings`, `rpc`,
`task`, `fs`, `clock`, `sum_tree`, and `fuzzy` — all of which are needed
for buffer integration (`Buffer`, `SyntaxMap`, `Outline`,
`DiagnosticSet`) but not for grammar parsing or language configuration.
Extracting the core types lets downstream consumers depend on
`language_core` without pulling in the full integration stack.

## Dependency graph after extraction

```
language_core   ← gpui, lsp, tree-sitter, util, collections
grammars        ← language_core, rust_embed, tree-sitter-{rust,python,...}
language        ← language_core, text, theme, settings, rpc, task, fs, ...
languages       ← language, grammars
```

## What moved to `language_core`

- `Grammar`, `GrammarId`, and all query config/builder types
- `LanguageConfig`, `LanguageMatcher`, bracket/comment/indent config
types
- `HighlightMap`, `HighlightId` (theme-dependent free functions
`highlight_style` and `highlight_name` stay in `language`)
- `LanguageName`, `LanguageId`
- `LanguageQueries`, `QUERY_FILENAME_PREFIXES`
- `CodeLabel`, `CodeLabelBuilder`, `Symbol`
- `Diagnostic`, `DiagnosticSourceKind`
- `Toolchain`, `ToolchainScope`, `ToolchainList`, `ToolchainMetadata`
- `ManifestName`
- `SoftWrap`
- LSP data types: `BinaryStatus`, `ServerHealth`,
`LanguageServerStatusUpdate`, `PromptResponseContext`, `ToLspPosition`

## What stays in `language`

- `Buffer`, `BufferSnapshot`, `SyntaxMap`, `Outline`, `DiagnosticSet`,
`LanguageScope`
- `LspAdapter`, `CachedLspAdapter`, `LspAdapterDelegate` (reference
`Arc<Language>` and `WorktreeId`)
- `ToolchainLister`, `LanguageToolchainStore` (reference `task` and
`settings` types)
- `ManifestQuery`, `ManifestProvider`, `ManifestDelegate` (reference
`WorktreeId`)
- Parser/query cursor pools, `PLAIN_TEXT`, point conversion functions

## What the `grammars` crate provides

- Embedded `.scm` query files and `config.toml` files for all built-in
languages (via `rust_embed`)
- `load_queries(name)`, `load_config(name)`,
`load_config_for_feature(name, grammars_loaded)`, and `get_file(path)`
functions
- `native_grammars()` for tree-sitter grammar registration (behind
`load-grammars` feature)

## Pre-cleanup (also in this PR)

- Removed unused `Option<&Buffer>` from
`LspAdapter::process_diagnostics`
- Removed unused `&App` from `LspAdapter::retain_old_diagnostic`
- Removed `fs: &dyn Fs` from `ToolchainLister` trait methods
(`PythonToolchainProvider` captures `fs` at construction time instead)
- Moved `Diagnostic`/`DiagnosticSourceKind` out of `buffer.rs` into
their own module

## Backward compatibility

The `language` crate re-exports everything from `language_core`, so
existing `use language::Grammar` (etc.) continues to work unchanged. The
only downstream change required is importing `CodeLabelExt` where
`.fallback_for_completion()` is called on the now-foreign `CodeLabel`
type.

use Mix for code formatting, so these instructions are only useful if
you work _without_ a language server
- Adjust Tailwind LSP configuration instructions

## How to Review

Check for typos and that the wording/structure of the new/reworded
sections is also good.

Although search_on_input is a merged feature, it doesn't look like it's
live yet. As a result, some people might be trying to activate the
feature without success.

This commit removes its reference from the docs.

As of https://github.com/zed-industries/zed/pull/50750, the runner size
for building the extension CLI is no longer sufficient due to the
addition of the `settings_content` crate as a dependency. The [most
recent workflow
run](https://github.com/zed-industries/zed/actions/runs/23554506504/job/68577404831)
fails while building that crate due to insufficient RAM availlable
during the build.

Removing the dependency is not an option, as we do want to have the
validation here and need structs from the settings content crate to do
so.

Thus, changing the job here to a larger runner to fix the build and also
build it faster.

Release Notes:

- N/A

These comments come from the scaffolding script for new crates, yet are
no longer relevant in the given files. Thus, just removing them here to

This PR refactors the highlight map capture name resolution to be faster
and more predictable. Speficically,
- it changes the capture name matching to explicit prefix matching
(e.g., `function.call.whatever.jsx` will now be matched by only
`function`, `function.call`, `function.call.whatever` and
`function.call.whatever.jsx`). This matches the behavior VSCode has
- resolving highlights is now much more efficient, as we now look up
captures in a BTreeMap as opposed to searching in a Vector for these.

This substantially improves the performance for resolving capture names
against themes. With the benchmark added here for creating the
HighlightMap, we see quite some improvements:
```

                        Performance has improved.
Found 1 outliers among 100 measurements (1.00%)
  1 (1.00%) low mild
```

For large themes and many capture names, the revised approach is much
faster.

With that in place, we can also add better fallbacks whenever we change
tokens, since e.g. a change from `@variable` to `@preproc` would
previously cause tokens to not be highlighted at all, whereas now we can
add fallbacks for such cases more efficiently. I'll add this later on to
this PR.

Release Notes:

- Improved resolution speed of theme highlight capture names. This might
change highlighting in some rare edge cases, but should overall make
highlighting more predicatable. Theme captures will now follow a strict
prefix matching, so e.g. function.call.decorator.jsx` will now be
matched by only `function`, `function.call`, `function.call.decorator`
and `function.call.decorator.jsx` with the most specific capture always
taking precedence.

- Added only toggle ACP log expansion from header clicks

This change limits expand/collapse in open acp logs to header clicks
only, instead of the entire message row. It prevents accidental
expand/zoom toggles when users click or drag inside log text, making it
easier to select and copy debug information.

After GPU device recovery clears the atlas, the next frame could
re-present a stale scene via the needs_present path (which skips scene
rebuilding). The stale scene references texture IDs that no longer exist
in the cleared atlas, causing an index-out-of-bounds panic.

Fix this by setting a force_render_after_recovery flag when device
recovery completes. The platform refresh loop reads this flag and passes
force_render: true in RequestFrameOptions, ensuring GPUI rebuilds the
scene before presenting.

Fixes ZED-5QT

This PR adds Git status badges next to file names in the Project Panel,
following my older PR #49802
These are enabled by having "git_status" true.

Screenshot

src="https://github.com/user-attachments/assets/b2c208bf-5027-4947-a5ee-eeb74fadb02b"
/>

I'd love to hear feedback about any of this :)
Especially feedback on these:

- File name colour is determined only by Git status, the diagnostic
badges remain separate. Should diagnostics also affect the filename
colour?
- (Unstaged) Modified files and staged modifications share the same
colour, in vscode staged modifications use a brownish colour by default
which I could not find the colours. I think differentiating them is
definetely something to add.

Release Notes

- Added git status indicators in Project Panel. It can be enabled by
setting `git_status_indicator` to `true` in `project_panel` settings.

Closes #52391

gopls sends semantic tokens for format args with [format] modifier.
Without a simple support for there is no special highlighting for format
args like `%s`. Its a simple change inside
`go/semantic_token_rules.json` that makes this a default behavior.

## Summary

- Added `TarBz2` variant to `AssetKind` enum for `.tar.bz2` / `.tbz2`
archives
- Implemented `extract_tar_bz2` using the `bzip2` feature of
`async-compression` (already a workspace dependency, just enabled the
feature flag)
- Wired up both streaming and file-based extraction paths in
`github_download.rs`
- Added `.tar.bz2` / `.tbz2` URL detection in both
`LocalExtensionArchiveAgent` and `LocalRegistryArchiveAgent`

This unblocks ACP registry entries (like Goose) that only ship
`.tar.bz2` archives.

Reference: https://github.com/block/goose/issues/8047

## Test plan

- [ ] Verify `cargo check` and `clippy` pass (confirmed locally)
- [ ] Test downloading an ACP agent that ships a `.tar.bz2` archive
(e.g., Goose)
- [ ] Verify existing `.tar.gz` and `.zip` agent downloads still work

Release Notes:

- Added support for `.tar.bz2` archives in ACP agent server downloads,
unblocking registry entries like Goose that only ship bzip2-compressed
tarballs.
