Refactored ModelFinder.go to scan directories once and build an in-memory index of filenames. This avoids repetitive I/O operations for each input filename. - Implemented pre-scanning of search paths. - Added filename-based index for O(1) lookup of non-wildcard queries. - Retained wildcard support via linear scan of cached paths. - Improved performance significantly (benchmark indicates ~16x speedup).
