BREAKING CHANGES:
- Remove timeLimit from GameOptions (use gameOver function instead)
- Remove finalScore from ScoreManager (pure data collection only)
- Remove rows/cols parameters from useScore
- Remove finalScore calculation logic from useScore hook
ADDITIONS:
- Create calculateMazeScore() utility function
- ScoreManager now only returns raw metrics: timeValue, keystrokes, optimalSteps, efficiency, distToKey, distToExit
- Score calculation moved to consumer (calculateMazeScore takes scoreManager + mazeSize)
- Example app now uses calculateMazeScore to compute final score on game-won
BENEFITS:
- ScoreManager is now a pure data collector with no side effects
- Scoring algorithm is reusable and testable in isolation
- Game-over conditions fully controlled via gameOver option
- Clear separation of concerns: collection vs calculation
