This PR adds a button in the `git: branch diff` view that allows to
quickly and easily send the entire diff to your last used agent for a
review. What this does is automatically submits a (pre-written and
generic) prompt to the last agents you were using in the agent panel
with the whole content of your diff.

Select toolchain path dialog immediately dismisses upon selecting a
path, preventing the addition of new toolchains

- OpenPathDelegate emits DismissEvents in the `confirm` function too
- when the selection is confirmed, DismissEvent is emitted
- ToolchainSelector calls cancel because it receives the DismissEvent,
and it goes to the Search State
- This prevents the selected toolchain from being resolved and the
ScopePicker being presented

cc: @JosephTLyons 

Release Notes:

- Fixed a regression where the toolchain path selector would immediately
dismiss upon selecting a path, preventing the addition of new
toolchains.

This PR implements the ability to undo the "reject all" action from the
agent panel (and the other places where this button is surfaced).
Effectively, this allows to recuperate the edits an agent has introduced
in case you either accidentally clicked the button or regretted the
decision to reject all.

Now that the cloud-side StreamEnded support has landed, enable it on the
Zed client:

- Send the
`x-zed-client-supports-stream-ended-request-completion-status` header so
cloud knows to send `StreamEnded` status events.
- Track whether `StreamEnded` was received during the stream.
- Emit `StreamEndedUnexpectedly` error when the stream closes without a
`StreamEnded` status, indicating the response was truncated.

Concretely, this means that the agent panel will now display an
abnormally terminated response stream for model calls through a Zed
subscription as an error instead of just stopping.

Add icon decorations on the agent icon in the sidebar to show thread
status:

- **Generation done**: blue dot (existing behavior, unchanged)
- **Blocked on tool permission/confirmation**: yellow warning triangle
- **Thread stopped due to an error**: red X

Priority order for decorations: confirmation > error > done > running
spinner.

Confirmation and error decorations persist as long as the thread is
actually in that state and always show regardless of whether the
workspace is active (unlike the blue dot which is notification-based).

(No release notes because this is all feature-flagged.)

Release Notes:

- N/A

Fix several issues with multi-workspace serialization and restoration
that caused sidebar workspaces to not fully restore after Zed restart.

## Changes

### 1. Resilient restoration — don't let one failing workspace kill the
rest

In `restore_multiworkspace`, the loop restoring each workspace in a
group used `?` on every `.await`. If any single workspace failed (e.g. a
DB read error, item deserialization failure), all remaining workspaces
were silently abandoned. Changed to log-and-continue so each workspace
is attempted independently. `restore_multiworkspace` now returns a
`MultiWorkspaceRestoreResult` containing both the window handle and a
list of errors, which the caller logs individually.

### 2. Proper serialization at lifecycle events

- **`create_workspace`** now assigns a database ID (via `next_id()`) and
writes a `session_id`/`window_id` binding so newly-created workspaces
can be persisted and restored.
- **`remove_workspace`** now deletes the removed workspace from the DB
(preventing zombie restoration) and serializes the updated
multi-workspace state.
- **`activate`** now only serializes when the active workspace actually
changes, and uses the new `set_active_workspace` helper to keep the
ordering correct (set index *then* serialize, not the other way around).
- The `serialize` method now stores its task in `_serialize_task`
instead of fire-and-forget detaching, enabling `flush_serialization` to
await it.

### 3. Flush serialization on quit

The quit handler now calls `flush_serialization` on every workspace and
multi-workspace before `cx.quit()`, bypassing the 200ms throttle to
ensure all `session_id`/`window_id` values are written to the database
before the process exits.

### 4. Await pending tasks on app quit

`MultiWorkspace` now registers an `on_app_quit` handler that awaits all
in-flight serialization, creation, and removal tasks within GPUI's
shutdown timeout. The existing `on_release` handler continues to detach
tasks as a safety net for non-quit window closes, matching the pattern
used by `Room`.

### 5. Track workspace serialization task

`Workspace::serialize_workspace` now stores the actual serialization
task in `_serialize_workspace_task` instead of detaching it, so
`flush_serialization` can cancel any pending throttle *and* await the
in-flight write.

### 6. New persistence helper

Added `set_session_binding` query to update a workspace's `session_id`
and `window_id` in one shot, used by `create_workspace` to bind
newly-created workspaces to the current session.

### 7. Tests

Added tests covering:
- `flush_serialization` completing before quit
- `create_workspace` assigning a DB ID and serializing the active
workspace ID
- Removal of a workspace deleting it from the DB and updating
multi-workspace state
- Restoration resilience when individual workspaces fail

Reverts zed-industries/zed#49478

Redirects to `/dev/null` (e.g. `2>/dev/null`, `&>/dev/null`) are
known-safe I/O routing, not commands. Previously, `extract_commands`
emitted normalized redirect strings like `"2> /dev/null"` as separate
entries in the command list checked against auto-allow regexes. Since
`check_commands` requires **all** extracted entries to match an allow
pattern, the unmatched redirect caused false-negatives — e.g. `git log
--oneline -20 2>/dev/null || echo ...` would not be auto-allowed despite
matching `^git` and `^echo` patterns.

Rather than removing all redirects from extraction (which would hide
dangerous redirects like `> /etc/passwd` from deny/confirm pattern
checking), this fix surgically skips only `/dev/null` targets during
redirect normalization. Redirects to real files are still emitted and
still require a matching pattern for auto-allow, preserving the
defense-in-depth property.

Closes AI-41

Release Notes:

- Fixed terminal auto-allow patterns incorrectly prompting for
confirmation on commands containing `/dev/null` redirects (e.g.
`2>/dev/null`).

This PR fixes issues with subagent cancellation, prior to this we would
still show a wait indicator for subagents that were cancelled from the
parent thread. We also removed the `stop_by_user` workaround, that code
path now uses `thread.cancel` directly

This PR removes onboarding modals for features that were announced, at
this point, a long time ago: Git v1, Debugger, and Agent Panel v1. This

ones, but we should be able to remove them soon enough, too.

Adds scripts and a GitHub Action workflow for automatically suggesting
documentation updates when PRs modify user-facing code.

## Scripts

- **`script/docs-suggest`**: Analyze PRs/commits for documentation needs
using AI
- **`script/docs-suggest-publish`**: Create a PR from batched
suggestions
- **`script/docs-strip-preview-callouts`**: Remove Preview callouts when
shipping to stable
- **`script/test-docs-suggest-batch`**: Testing utility for batch
analysis

## Workflow

The GitHub Action (`.github/workflows/docs_suggestions.yml`) handles two
scenarios:

1. **PRs merged to main**: Suggestions are batched to
`docs/suggestions-pending` branch for the next Preview release
2. **Cherry-picks to release branches**: Suggestions are posted as PR
comments for immediate review

## Callout Types

The system distinguishes between:

- **Additive features** (new commands, settings, UI):
  ```markdown
> **Preview:** This feature is available in Zed Preview. It will be
included in the next Stable release.
  ```

- **Behavior modifications** (changed defaults, altered existing
behavior):
  ```markdown
> **Changed in Preview (v0.XXX).** See [release notes](/releases#0.XXX).
  ```

Both callout types are stripped by `docs-strip-preview-callouts` when
features ship to stable.

## Example Output

See PR #49190 for example documentation suggestions generated by running
this on PRs from the v0.224 preview window.

## Usage

```bash
# Analyze a PR (auto-detects batch vs immediate mode)
script/docs-suggest --pr 49100

# Dry run to see assembled context
script/docs-suggest --pr 49100 --dry-run

# Create PR from batched suggestions
script/docs-suggest-publish

# Strip callouts for stable release
script/docs-strip-preview-callouts
```

Currently, the next chunk is generated by traversing all characters of
the current folded chunk until a tab is found. Since we already have
bitmasks for characters and tabs, we can also propagate the newlines
bitmap from the rope and use it to make this computation O(1) in all
cases.

## Summary

Comprehensive remediation of 146 documentation files to align with Zed's
documentation conventions and brand voice guidelines.

## Changes

### YAML Frontmatter
- Added `title` and `description` frontmatter to all docs missing it

### Settings UI Pattern
- Updated 48+ files to show Settings Editor before JSON examples
- Pattern: `Configure X in Settings ({#kb zed::OpenSettings}), or add to
your settings file:`
- Added `([how to edit](./configuring-zed.md#settings-files))` links for
JSON-only settings

### Brand Voice Fixes
- Removed exclamation points (command-palette, key-bindings, repl,
privacy-and-security, etc.)
- Simplified em dash chains to parentheticals (environment,
troubleshooting, agent-panel, etc.)
- Fixed marketing language (yarn.md intro, development/linux.md)

### Terminology Alignment
- `settings UI` -> `Settings Editor`
- `sidebar` -> specific panel names (Project Panel, Collab Panel)
- `directory` -> `folder` in non-technical contexts
- `workspace` -> `project` in non-LSP contexts
- `Command Palette` -> `command palette` (lowercase)

### Callout Standardization
- Converted various callout formats to standard `> **Note:**` pattern

## Related

Depends on conventions established in #49176.

Previously, clicking "Always allow for `cargo` commands" after running
`cargo build --release` would also silently permit `cargo run`
(arbitrary code execution), `cargo publish`, and any other cargo
subcommand. This was overly broad and did not match user intent.

Now the extracted pattern includes the subcommand when present, so the
button reads "Always allow for `cargo build` commands" and the pattern
`^cargo\s+build\b` only matches `cargo build` invocations — not `cargo
test`, `cargo run`, etc.

### How it works

- The second token is included in the pattern when it looks like a
subcommand (alphanumeric, hyphens, underscores, no leading `-`).
- When the second token is a flag (e.g. `ls -la`), only the command name
is used — the user sees "Always allow for `ls` commands".
- Single-word commands and path-like commands behave the same as before.

### Examples

| Command | Pattern | Button label |
|---|---|---|
| `cargo build --release` | `^cargo\s+build\b` | Always for `cargo
build` commands |
| `cargo test -p search` | `^cargo\s+test\b` | Always for `cargo test`
commands |
| `npm install` | `^npm\s+install\b` | Always for `npm install` commands
|
| `ls -la` | `^ls\b` | Always for `ls` commands |
| `ls` | `^ls\b` | Always for `ls` commands |
| `./script.sh` | *(rejected)* | *(no pattern button)* |

Release Notes:

- Agent: "Always allow" suggestions for terminal commands are now
subcommand-specific (e.g. "Always allow for `cargo build` commands"
instead of "Always allow for `cargo` commands").

This allows us to just pull requests that have the latest EP request
schema with the `predicted` boolean on events in the edit history.
