feat(performance): implement Phase 3.3 performance optimization for production

- Add DailyNotificationPerformanceOptimizer for Android with comprehensive optimization
- Add DailyNotificationPerformanceOptimizer for iOS with Swift performance management
- Implement database query optimization with indexes and PRAGMA settings
- Add memory usage monitoring with automatic cleanup and thresholds
- Implement object pooling for frequently used objects to reduce allocation
- Add battery usage tracking and background CPU optimization
- Add network request optimization and efficiency monitoring
- Add comprehensive performance metrics and reporting
- Add production-ready optimization with stress testing support
- Add phase3-3-performance-optimization.ts usage examples

This implements Phase 3.3 performance optimization for production reliability:
- Database indexes for query optimization (slot_id, fetched_at, status, etc.)
- Memory monitoring with warning/critical thresholds and automatic cleanup
- Object pooling for String, Data, and other frequently used objects
- Battery optimization with background CPU usage minimization
- Network request batching and efficiency improvements
- Comprehensive performance metrics tracking and reporting
- Production-ready optimization with configurable thresholds
- Cross-platform implementation (Android + iOS)
