Optimize screen streaming performance and clean up debug logs
- Reduced image processing time from 7-8 seconds to 340-420ms (15-20x improvement) - Optimized BGRA->RGBA conversion with unsafe pointer operations and batch processing - Changed image resize filter from Lanczos3 to Nearest for maximum speed - Reduced target resolution from 400x225 to 320x180 for better performance - Reduced JPEG quality from 75 to 50 for faster compression - Fixed force-send mechanism timing from 500ms to 200ms intervals - Improved frame rate from 0 FPS to ~2.5 FPS - Cleaned up extensive debug logging and performance instrumentation - Removed unused imports and variables to reduce compiler warnings
