feat: add runtime gameInfo enrichment with gameOver condition

- Add gameOverCondition to GameManager for runtime tracking
- Create enrichGameInfo() function to merge runtime condition with static gameInfo
- Add formatGameOverCondition() utility to stringify boolean/function conditions
- Returns enriched info with:
  - condition: formatted string representation
  - type: 'none' | 'static' | 'function'
- Platform can call enrichGameInfo(gameManager) to get complete game configuration
- Handles all condition types: undefined, boolean, function
- Truncates long function strings at 200 chars
