- Fixed frame index calculation in capturer.py to prevent invalid -1 index
- Removed side-effect of automatic settings load in globals.py; added explicit init()
- Refactored functions to accept config params directly, reducing global settings reliance:
- find_cluster_centroids() now takes max_k and kmeans_init
- NSFW prediction functions now accept threshold
- Updated documentation for all affected functions
- Verified all changes against existing test suite — all tests pass
