FINAL FPS FIX: Remove ALL Performance Optimizer Overhead

CRITICAL FPS FIXES:
- Removed performance_optimizer import from live_face_swapper.py
- Fixed broken performance_optimizer references causing overhead
- Removed swap_face_enhanced import (not needed)
- Cleaned up all performance optimization code

 OVERHEAD REMOVED:
- No more performance_optimizer.quality_level calls
- No more performance_optimizer.detection_interval calls
- No more complex performance tracking
- Pure, clean face swapping only

 EXPECTED RESULT:
- Should restore original 13+ FPS performance
- No performance optimization overhead
- Clean, fast face swapping
- Maximum speed priority

 FPS PROGRESSION:
- Original: 13+ FPS
- With complex code: 7 FPS
- After first fix: 9 FPS
- Now (all overhead removed): Should be 13+ FPS

 WHAT'S LEFT:
- Pure face detection and swapping
- No performance monitoring overhead
- No complex processing
- Maximum FPS operation
