Add hooks for interrupted turns (#40511)

## What changed

- Add an `Interrupt` hook event that runs for an active top-level turn before its
  interrupted abort event is emitted.
- Flush the turn transcript before invoking the hook and provide the session,
  turn, transcript, working directory, model, and permission mode in its input.
- Support command and MCP handlers, including asynchronous commands, with a
  one-second default timeout and a three-second maximum.
- Expose the event through hook configuration, managed requirements, app-server
  notifications, generated schemas, analytics, and the TUI hook views.

## Testing

- Cover handler discovery, timeout normalization, output parsing, protocol
  compatibility, TUI rendering, and interrupt execution ordering.
