I deliberately decided against adding this in a separete job because
ts_query_ls is very fast when it comes to both formatting these as well
as checking for proper formatting. Will see here how long it takes to
install and whether we might need to adjust to account for the
installation time.

This reverts commit aa3a12b566, because we no longer want a zoomed item
to block the sidebar.

This is because the sidebar is used for navigation and it interrupts a
user's flow if they're scrolling through their active workspaces, and
the sidebar just vanishes.

We now stream the new text into the buffer as soon as we receive partial
chunks of `new_text`. This is pretty much a full re-write of the way
streaming worked, which is now much closer to how the edit agent works:
- `ToolEditParser` buffers chunks as they stream in, and emits relevant
events (`OldTextChunk`,`NewTextChunk`, ...) that we use to power the
`EditSession` pipeline.
- `EditSession::process_events` takes care of consuming these events and
applying the edits incrementally as chunks stream in. `EditPipeline`
maintains the underlying state machine for each edit.
- We handle whitespace mismatches similar to the edit agent, the code is
shared by moving that logic to `reindent.rs`

Turns out you can't query the duplicate issue for the id of the
original/canonical issue, even though GitHub UI displays “Closed as
duplicate of <original issue id>”. Oh well. For the bot performance
tracking all that matters is whether any of its suggestions were the
actual originals, so we're working around the API limitation by querying
the suggested issues instead.

Release Notes:

- N/A

Obviously™, we add the bot-commented issues onto the tracking board at
the time of the issues getting closed, which is very much not the same
time as when the bot commented. We could very well be adding the issue
with a v1 bot comment to the board when v2 is already deployed. This
commit stops messing up those stats.

## Summary

- Tighten `link_pattern_file_candidates` regex from `\(([^)]*)\)` to
`]\(([^)]*)\)` so only Markdown link syntax `[title](path)` triggers
path extraction from parentheses
- Prevents function call arguments like `do_work(file2)` from being
incorrectly resolved as file paths, which preempted LSP go-to-definition

Closes #48938

## Test plan

- [x] `cargo test -p editor hover_links` — all 12 tests pass
- [x] New unit tests verify: function calls don't extract arguments as
file candidates; Markdown links still extract correctly

## Problem
Zed's ACP config-options UI was only rebuilding selectors when the set
of config option IDs changed.

For many model switches, the IDs stay the same (`mode`, `model`,
`reasoning_effort`) while the valid values for `reasoning_effort` change
by model. As a result, the picker could show stale values (for example,
missing `xhigh` on `gpt-5.3-codex`, or showing extra `xhigh` after
switching away).

This is especially problematic for providers like Copilot that expose
multiple agents/models with different reasoning-level capabilities.

## Fix
Rebuild ACP config-option selectors on every `config_option_update`, not
only when config IDs change.

This refreshes cached picker entries whenever model-specific option
values change, even if option IDs are unchanged.

## User Impact
- Reasoning-effort picker now reflects the selected model immediately on
Claude <-> GPT transitions.
- Prevents stale or invalid effort choices in ACP sessions.

## Validation
- Manual validation: switch across models with different
reasoning-effort sets and confirm picker updates immediately.
- Local `cargo check -p agent_ui` remains blocked by unrelated
pre-existing `livekit-protocol` compile errors in this checkout.

## Files Changed
- `crates/agent_ui/src/acp/config_options.rs`

Release Notes:

- acp: Fix for config selectors not always being refreshed

This is a staff only toggle for now, since the consequences of
activating it are not obvious and quite dire (tokens costs 6 times
more).

Also, persist thinking, thinking effort and fast mode in DbThread so the
thinking mode toggle and thinking effort are persisted.

Release Notes:

- Agent: The thinking mode toggle and thinking effort are now persisted
when selecting a thread from history.

From the looks of it, this setting was never used by the File Finder. It
also doesn’t make much sense to show git info in the File Finder. The
Project Panel already exposes this information to the user.

Closes #49709.

`.prettierrc` can be [written](https://prettier.io/docs/configuration)
in either JSON or YAML. Whether you write JSON or YAML, VS Code will
default to recognizing it as JSON. See screenshot.

Without this change, the user is forced to do:

```jsonc
"file_types": {
  "JSON": [".prettierrc"],
},
```

Small QoL improvement.

Handles a panic found in telemetry - when there are no template matches
or feature matches, the picker delegate will panic due to an indexing
exception. This solves by:
1. Returning early if there are no matches, and
2. Performing safe vector `get` operations instead of slicing, so we can
handle a not-found scenario.

Release Notes:

- Fixed potential crash from initializing devcontainer.json

`send_file_drop_event` was the only event dispatch site in window.rs
that called the event callback while still holding the `MacWindowState`
mutex. every other callback site in the file uses the established
`take() / drop(lock) / callback()` pattern which releases the lock
before invoking user code.

this is a latent code quality issue: no deadlock occurs today because
the current file-drop callback chain does not reenter `MacWindowState`'s
mutex (`Window::mouse_position()` returns a cached field
`Window::refresh()` only marks a dirty flag and `cx.activate()` uses a
separate `MacPlatform` mutex). but `parking_lot::Mutex` is not entering
so any future platform call added inside a filedrop handler would
deadlock immediately and silently.

the fix brings `send_file_drop_event` in line with the rest of the file
by taking the callback out of the state dropping the lock invoking the
callback then reacquiring the lock to restore the callback and update
state.

- N/A

- The stack trace multibuffer view has been removed.

Refactor buffer search bar click handler to use listener pattern

The click handler for the buffer search bar now uses the `cx.listener`
pattern instead of directly dispatching the action. This approach
properly binds the action handler to the component's context and ensures
consistent behavior with other event handlers in the codebase.

“dev: open highlights tree view” is useful for inspecting semantic
tokens. To create a theme, custom-defined semantic rules and theme
settings are required and theme mappings can be difficult across
languages. This PR adds syntax(tree-sitter) tokens and their resolved
theme keys to tree view. It also updates semantic token entries to show
their resolved theme keys.
