- Removed calls to non-existent BBRegressor methods debug_get_conv3_1t_output and debug_get_conv4_1t_output in test/test_models.cpp.
- Restored correct BBRegressor processing logic using get_iou_feat, get_modulation, and predict_iou.
- This resolves build errors introduced by referencing methods that were never implemented.
- Build and test workflow now completes successfully.
