Improve AXe core functionality and reliability
- Clean up HIDInteractor by removing debug code and TODO comments
- Enhance FutureBridge with improved error handling and type safety
- Add StandardError utility for consistent error handling
- Update AccessibilityFetcher with better JSON output formatting
- Improve Swipe command with production-ready comments
- Add comprehensive timing controls across commands
- Remove race condition issues through better async/await patterns
Core Improvements:
- ✅ Production-ready code with debug artifacts removed
- ✅ Enhanced error handling and validation
- ✅ Improved async/await patterns for reliability
- ✅ Better type safety in framework bridging
- ✅ Consistent logging and output formatting
