fix: resolve shiny icon detection by fixing BGR/RGB color channel swap

Fixed critical color conversion issue where RGBA2RGB was causing red/blue
channel swap, preventing YOLO model from recognizing shiny icons. Changed
to RGBA2BGR conversion for proper OpenCV compatibility.

Key improvements:
- Fixed screen capture padding/cropping (1088→1080px width)
- Added comprehensive debug logging for capture pipeline
- Created comparative debugging scripts for .pt vs ONNX models
- Resolved color corruption preventing shiny icon detection
- Shiny icons now detected with 0.87+ confidence

Testing confirmed detection working for shiny icons and other UI elements.
