      summary: Rename a chat room
      description: 'Renames a chat room the acting agent owns. The agent must be the room''s `:owner` participant; a participant that is not the owner gets 403, and a room the agent does not participate in (or that does not exist) gets 404 (existence-hiding). Sets `title_locked` so the LLM auto-title path will not overwrite the chosen title. Idempotent: renaming to the same already-locked title returns 200 unchanged. Title is trimmed; must be 1..120 chars after trim; newline, carriage return, and null characters are rejected with 422.'
