This adds Claude Opus 4.6 as a new Anthropic model, along with 1M
context window variants for both Opus 4.6 and Sonnet 4.5.

## Opus 4.6

Adds `ClaudeOpus4_6` and `ClaudeOpus4_6Thinking` with the same
properties as other Claude 4+ models (200k context, 8192 max output
tokens, fine-grained tool streaming beta header).

## 1M context variants

Adds 1M context window variants for Sonnet 4.5 and Opus 4.6. These are
identical to their base models except:
- Context window is 1,000,000 tokens instead of 200,000
- They send the `context-1m-2025-08-07` beta header

Release Notes:

- Added Claude Opus 4.6
- Now Claude Opus 4.6 and Sonnet 4.5 BYOK models support variations that
have context windows of 1 million tokens (and have different pricing)

### Summary
Adds accept/reject tracking for Mercury edit predictions.

### Changes
Sends events to https://api-feedback.inceptionlabs.ai/feedback when:

Accept — user presses Tab
Reject — user presses Escape
Ignore — prediction dismissed implicitly (typing, cursor move, etc.)

Added `discard_explicit` method to the delegate trait to distinguish
explicit vs implicit dismissal. Updated `reject_prediction` and
`reject_current_prediction` methods with an `explicit` bool parameter to
thread this through to the Mercury feedback logic. Other providers are
unaffected—they use the default implementation.

Feedback is fire-and-forget in a background thread, only sent for
predictions that were shown.

### Data Collected
- Request ID (returned from Inception API)
- User action (either accept/reject/ignore)
- Client Zed version (to track updates made to Zed client which could
potentially affect nextedit implementation)

Closes ZED-4R9

Introduced in https://github.com/zed-industries/zed/pull/47768

The `insert_context_prefix` function was using byte offsets to check if
the prefix already exists at the cursor. This caused a panic with
multi-byte characters like emojis. Now uses character counts instead.

Release Notes:

- Fixed a crash in the Agent Panel when inserting context mentions with
emojis in the message editor.

I'm used to having the Emacs mark-sexp command, which selects/extends
the selection to the start or end of a sexp/larger syntax node, so when
I found out the `move to {start,end} of larger syntax node` commands
were added, these seemed like a natural addition; especially since most
other commands in Zed seem to have movement and selection pairs, but
those didn't really feel like they did.

I did a really *lot* of tests (brainstormed ideas with GLM 4.7, then
wrote the actual test case strings myself, then had it convert them to
Rust, then made sure the tests made sense and passed), I'm not sure if
it's too much or too little, but I looked at the PR that added the `move
to` versions of these commands and it was also +~550 lines, so this
seemed in the ballpark 😅

I factored out the core syntax node finding logic from those commands
into a common function, so that both sets of commands could use it, just
with different code for modifying the editor state wrapped around — mine
just moves each selection's head, instead of totally resetting it.

Release Notes:

- Added commands for extending selections to syntax node boundaries.
i.e. `editor: select to start of larger syntax node` and `editor: select
to end of larger syntax node`.

Basically just replaced `SharedString::new("` with
`SharedShring::new_static("` which removes the allocation to `Arc<str>`.

Unfortunately this can't be enforced at compile time without trait
specialization which is only available on nightly. You could assert that
`TypeId`'s differ, but `TypeId` only exists at runtime.

When working in a workspace with multiple repositories, the git panel
provides a repository picker to switch between them. However, there was
no visual indication of which repositories have uncommitted changes:
users had to either select each repository individually or check the
project panel where modified directories are highlighted.

This change adds git status icons to the repository picker, allowing
users to see at a glance which repositories contain changes (modified,
added, deleted, or conflicted files). The icons use the same visual
language already established for file status throughout the git panel.

Additionally, the repository picker now matches the branch picker's
styling for visual consistency:
- Added "Repositories" header
- Aligned popover width and positioning
- Added scrollbar
- Added check icon next to currently selected repo
- Added selected branch under repo list item
- Sort by display name is now case insensitive

This PR adds a check during extension compilation to ensure that every
compiled extension provides at least one feature, as otherwise, the
extension is useless to have.

fail.

This PR adds the upsell banner for built-in agents in the ACP registry
page, meaning: if you search for Claude Code, Codex, or Gemini, we'll
display a banner communicating they're already available in Zed. This
may change one day, though, whenever we rely on their registry
implementation. I'm also removing the beta chip from the page here.

Previously, double-click word selection in markdown used simple
space-based boundaries, so `foo.bar()` would be selected as a single
word.

Now we use `CharClassifier` which properly handles word boundaries:

- **Regular markdown text**: Punctuation (`.`, `(`, `)`, etc.) now acts
as word boundaries. Double-clicking on `foo.bar()` selects just `foo` or
`bar`.
- **Code blocks**: Uses the language's word characters. For example, in
JavaScript, `$foo` and `#bar` are selected as whole words since `$` and
`#` are configured as word characters.

Release Notes:

- Improved double-click word selection in Agent Panel to respect
punctuation and language-specific word characters.

Several libcpp headers lack file extensions. Added a first line pattern
for recognition.

Release Notes:

- Added first-line C++ language detection for extensionless libcpp
headers.

`LanguageServerSeed` is used as a key to identify language servers.
Previously, it included the entire `LspSettings`, which meant that
changing `lsp.<server>.settings` (dynamic configuration) would cause the
server to restart unnecessarily.

Dynamic settings can be updated via LSP's
`workspace/didChangeConfiguration` notification without requiring a
server restart. Only `binary` and `initialization_options` should be
part of the server identity, as changes to these genuinely require
restarting the server.

This is a follow-up fix to #35270 which introduced `LanguageServerSeed`
but inadvertently included dynamic settings in the server identity
(although I remember that this dynamic settings reflection stopped
working pretty recently, so there might be other commits besides #35270
that changed the behavior of `LanguageServerSeed`)

Closes #ISSUE

Release Notes:

- Fixed language servers unnecessarily restarting when changing
`lsp.<server>.settings` configuration. Dynamic settings are now properly
updated via `workspace/didChangeConfiguration` without requiring a
server restart.

Release Notes:

- Added highlighting for document comments in C/C++

## Summary

Adds three syntax highlighting captures that are used across multiple
language definitions but were missing from the documentation table in
`docs/src/extensions/languages.md`.

## Added Captures

| Capture | Used In |
|---------|---------|
| `@constant.builtin` | C, Go, C++, YAML, TSX |
| `@type.builtin` | C++, Python, Rust, JavaScript, TSX |
| `@variable.parameter` | TypeScript, JavaScript, Python, Rust, TSX,
Diff |

## Context

While working on a [PR to add named argument highlighting to the PHP
extension](https://github.com/zed-extensions/php/pull/95), I initially
used `@label` because the documentation didn't list
`@variable.parameter`. A reviewer pointed out that `@variable.parameter`
is actually supported and preferred - the docs were just outdated.

This PR fixes that documentation gap.

Closes #ISSUE

Release Notes:

- (preview only) Fixed typing emoji using the macOS system palette
(cmd-ctrl-space)

This setting brings Zed in parity with Sublime's `bold_folder_labels`.

The settings does just that, it makes directory labels bold. This
setting is
particularly useful for those who turn icons off, but do need a visual
queue (besides the chevron) to quickly tell apart files and folders.

Note: This PR depends on
https://github.com/zed-industries/zed/pull/47629.
Otherwise, the setting will appear to have no uneffect (unless you're
using a custom UI font). ZedSans has "bold" today, but that's too thick
for the project panel.

Release Notes:

- Added `project_panel.bold_folder_labels` to show folder names with
bold text in the project panel (defaults to `false`).

Following user feedback, this should help making the Markdown Preview
more discoverable.
