Two bugs fixed:
- Piece <img> elements were intercepting pointer events, preventing
dnd-kit drag handlers and square click handlers from firing. Added
pointerEvents: "none" so events pass through to the board framework.
- Solo test mode (fillRoom with duplicate player IDs) always resolved
to "white" in colorOfPlayer, making black moves impossible. Now
detects duplicate IDs and returns the current turn's color instead.

Add chess as the first game plugin using the existing multiplayer framework.
Server-side game logic uses chess.js with server-authoritative clock management.
Client uses react-chessboard v5 with cburnett piece set, drag-and-drop + click-to-move,
configurable time controls (bullet/blitz/rapid/classical/none), draw offers,
resignation, and timeout detection. Extends the game framework with room creation
options to support per-game configuration. Includes 57 tests covering all code paths.
