✨ Major code reorganization for better maintainability:

📁 NEW CONTROLLERS CREATED:
• GameController.js - Handles game logic, cards, turns, matching
• TimerController.js - Manages time tracking and elapsed time
• AudioController.js - Centralizes all sound effects management
• ScoreController.js - Handles scoring, high scores, game completion
• HintController.js - Manages hint system and cooldowns
• ErrorController.js - Provides error handling and logging
• index.js - Clean exports for easy importing

🔧 IMPROVEMENTS:
• Reduced App.js complexity from 323+ lines
• Separated concerns for better code organization
• Enhanced maintainability and readability
• Easier testing and debugging
• Prepared for future feature additions
• Following React best practices

🎮 FUNCTIONALITY:
• All existing features work exactly the same
• No breaking changes for users
• Improved developer experience
• Ready for Hacktoberfest contributions

This refactoring makes the codebase more modular and easier
for contributors to understand and extend.
