Adds a full blackjack game with dealer AI, hit/stand/double-down actions,
and per-player payout multipliers (house-edge model). Extends the game
framework with manualStart support and a START_GAME WebSocket message so
hosts can begin when ready. Generalizes bet settlement transaction
descriptions from chess-specific to game-agnostic.

Replace external SVG files loaded via <img> tags with inline React SVG
components. The <img> approach was a DOM-level problem — replaced elements
sit outside React's tree and interfere with dnd-kit's pointer event
pipeline. Inline SVGs are native JSX nodes that participate correctly
in event bubbling, matching how react-chessboard's default pieces work.
Removes panel/public/pieces/ (12 SVG files) in favor of a single
pieces.tsx module with the same cburnett artwork as JSX.

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.
