Phase 4: UI and UX Polish - Complete

✨ Features Added:
• Animated background gradients for relaxing visual effects
• Settings screen with music and haptics toggles
• Tutorial overlay with step-by-step guidance
• Haptic feedback on all interactions (with graceful fallback)
• Enhanced main menu with settings button
• Immersive background animations in both menu and game

🎨 UI Improvements:
• Flowing gradient animations in background
• Settings management with SharedPreferences
• Tutorial system with progress indicators
• Smooth transitions and visual feedback
• Enhanced button interactions with haptics

🔧 Technical:
• Added shared_preferences for settings persistence
• Updated vibration package to v2.1.0
• Error handling for platform-specific features
• Fixed deprecation warnings (withOpacity -> withValues)
• Cross-platform compatibility improvements

Phase 4 implementation complete - UI and UX significantly enhanced!
