Updated tracking to support multi-lemon tracking

- Improved tracking logic to handle multiple lemons simultaneously
- Added necessary YAML configuration for BoT-SORT

Higher Sensitivity to Minor Defects:
- Weighted “DefectiveLemon” more heavily
- Extended HISTORY_LENGTH for improved tracking stability
