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.

Release Notes:

- N/A

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.

Full line selections should only include the next line if there's a
single line selected. Otherwise, if multiple lines are selected, only
the selected lines should be joined.

Also updates the editor tests to include both of these cases.

- Fixed `editor::JoinLines` when a multi-line selection includes the end
of the final line

The ACP monikers are left over from when we had two versions of

* Add a dedicated `vim.yank.background` theme color for the yank
  highlight, which was previously hardcoded to
  `editor.document_highlight.read_background`.
* When a theme doesn't define `vim.yank.background`, it falls back to
  `editor.document_highlight.read_background` for backwards
  compatibility.
* The VS Code theme importer maps `editor.rangeHighlightBackground` to
  this new color.

- Added configurable `vim.yank.background` theme color for vim yank

The mermaid renderer can fail to render certain diagrams, and we already
have a fallback for that. It's not worth crashing Zed over it.

Wrapping `catch_unwind` alone doesn't work because our panic hooks
terminate the process before unwinding begins (we intentionally
terminate so the crash handler subprocess can generate a minidump), so
there was no way to gracefully handle panics from third-party code until
now (in rare cases where we need it, like in this case).

To handle this gracefully, we added `crashes::recoverable_panic` which
tells the panic hook to stand down on the current thread so the unwind
can proceed and be caught. This should be used sparingly since caught
panics bypass crash reporting.

Release Notes:

- Fixed a crash when rendering mermaid diagrams in markdown preview.

Release Notes:

- N/A

## Summary

- Fix SSH `-L` port-forward arguments to wrap IPv6 addresses in brackets
(e.g. `-L[::1]:8080:[::1]:80`), so SSH can correctly parse them
- Rewrite `parse_port_forward_spec` to support bracket-wrapped IPv6
tokens like `[::1]:8080:[::1]:80`
- Add diagnostic logging for stdin read failures in the remote server to
aid debugging connection issues

Closes #49009

## Test plan

- [x] New unit tests: `test_parse_port_forward_spec_ipv6`,
`test_port_forward_ipv6_formatting`,
`test_build_command_with_ipv6_port_forward`
- [x] Existing tests pass: `cargo test -p remote --lib
transport::ssh::tests` (6/6)
- [ ] Manual verification: connect via SSH to an IPv6 host with port
forwarding configured

Release Notes:

## Summary

Fixes issues discovered while running the docs automation workflow for
the first time, plus improvements based on the v0.225 run where 44
suggestions overwhelmed a single Droid invocation.

### docs-suggest-publish
- Ignore untracked files when checking for clean working directory
- Add `--auto high` flag to droid exec for non-interactive use
- Add error handling to show droid output on failure
- Remove non-existent `documentation` label from PR creation
- Use `--write` flag for prettier to fix formatting
- **Batch suggestions** into groups of 10 (configurable with
`--batch-size`) to prevent Droid from dropping suggestions when context
is too large
- **Pre-PR docs build validation** — runs `generate-action-metadata` +
`mdbook build` before creating the PR to catch invalid `{#action}` and
`{#kb}` references locally instead of waiting for CI (skippable with
`--skip-validation`)
- **Prompt guardrail** — instructs Droid not to invent `{#kb}` or
`{#action}` references, only reusing action names already present in
docs files
- **Stable release detection** — at publish time, checks each queued
PR's merge commit against the latest stable release tag. PRs already in
stable get annotated "ALREADY IN STABLE" so Droid applies content
changes without adding incorrect Preview callouts
- **Feature flag detection** — parses
`crates/feature_flags/src/flags.rs` for all feature flag struct names,
then checks each PR's diff for references. PRs behind feature flags are
skipped entirely since those features aren't generally available yet

### docs-strip-preview-callouts
- Remove non-existent `documentation` label from PR creation
- Add `Release Notes: - N/A` to generated PR body (fixes Danger bot
check)

## Context

These scripts were run for the first time as part of the v0.225 release.
Issues found:
1. The `documentation` label doesn't exist in this repo
2. Droid exec needs `--auto high` for non-interactive execution
3. Prettier needs `--write` to actually fix files (was running in check
mode)
4. Untracked files should not block the workflow
5. Sending all 44 suggestions in one Droid invocation only applied 2 —
batching in groups of 10 fixed this
6. Droid hallucinated action names (`settings::OpenSettings`,
`gpui::Modifiers::secondary_key`) that broke the docs preprocessor build
7. PRs that shipped in stable v0.225 incorrectly got Preview callouts
because the queue doesn't distinguish preview-only from
already-in-stable
8. PRs behind feature flags (subagents, git graph) got documented
despite not being generally available

Release Notes:

- N/A

In some evals, the teacher produced hallucinations, seemingly due to
context rot. This makes the zeta prompt crate's budgeted rendering
usable by the teacher, so that it can truncate the list of excerpts.

I've also cleaned up the implementation of zeta_prompt's
`format_related_files_within_budget`, and changed the behavior so that
it filters the the excerpts by priority but renders the files in their
original order.

Release Notes:

- N/A

Now that MultiWorkspace is the root view, actions bound to the
`Workspace` key context wouldn't be dispatched when `Workspace` is not
in the key context stack (e.g. when the sidebar is focused). To fix
this, the `Workspace` key context and action handlers are moved up to
the MultiWorkspace rendering layer. This avoids introducing a new key
context and the keymap migration that would require.

This PR also moves modal rendering up a layer so modals are centered
within the window (MultiWorkspace element) instead of the Workspace
element.

I address my comments by adding a hash map look-up to find the selected
