The move endpoint now returns the full resulting board state, and the controller and CPU orchestrator broadcast it (plus captured pieces and a ply version) over SignalR, so clients render from one payload instead of re-fetching. Removes the client-driven hub relay. Co-Authored-By: Claude Opus 4.8 (1M context) <[email protected]>
