CLAUDE: Optimize play history sync to O(1) with setPlayHistory

Browse Source 
Replaced O(n²) deduplication check per play with O(1) array replacement:
- Added setPlayHistory() for game_state_sync (replaces entire array)
- Simplified addPlayToHistory() for live play_resolved events (just push)

This separates sync operations (replace) from live events (append),
eliminating the need for deduplication checks during gameplay.
