## Message

```
Emit agent thread status change events (#60057)

# Objective

Fix unreliable working/status indicators for ACP agent threads.

ACP threads update their internal running state when a turn starts,
completes, or is canceled, but those status-only changes were not being
emitted as thread events. The agent UI could miss transitions unless
another entry-related event happened nearby, making it particularly hard
to monitor the status of multiple agent threads running at once.

Hope this helps, and thanks for making Zed.

## Solution

- Add an `AcpThreadEvent::StatusChanged` event.
- Emit it when `running_turn` is set, cleared, or canceled.
- Have `ConversationView` handle the event by syncing the active thread
view's generating indicator.
- Treat status changes as UI state only, not root thread metadata
changes.

## Testing

- `cargo check -p sidebar -p project -p git_ui -p workspace`
- Manually verified in a local dev build on macOS that ACP agent
status/working indicators update reliably.

No automated test was added; this changes UI synchronization for ACP
thread status events.
