~x-ai/grok-latest → B (1:12)

B implements the full room-create CLI path, simplifies the core data model (drops ThreadVisibility/RoomState, rooms become a HashSet), and updates RPC/events/reducer/tests/docs accordingly—lasting product and design work. A only adds a missing GITHUB_API_BASE_URL default env var, a one-liner NameError fix with far less scope.
