search_library_courses was walking via list_library_directory, which computes a full recursive file count (rglob) and thumbnail lookup for every course at every level - turning a search into an O(every file in every course) scan regardless of how few results actually match. Give search its own lightweight directory-only walk and defer the expensive per-course lookups until after a name match is confirmed, so cost now scales with matches found rather than total library size.
