Performance and correctness improvements across model scanning, matching, workflow analysis, and CivitAI URL handling:
- Add short-lived in-memory cache for get_model_files (with force_rescan and invalidate_model_files_cache) to reduce frequent directory scans.
- Pass scanned available_models into workflow analysis to avoid rescanning and build category-indexed lists plus an ordered-candidates cache for faster candidate ordering.
- Improve analyze_and_find_matches to special-case urn:air: URNs (use filename suffix when present) and skip fuzzy matching when appropriate.
- Rewrite find_matches to maintain only the top N results via heapq, cache normalized candidate path/filename values on candidate dicts, and early-exit on max_results<=0 to reduce allocations and CPU.
- Add helper functions in CivitAI source to extract/build stable image page URLs (_extract_civitai_image_id, _build_civitai_image_url) and use them when populating image metadata.
- Propagate available_models into get_node_model_info and analyze_workflow_models so subroutines reuse the same scanned list.
- Guard frontend and backend folder lookups to return early for unknown categories to avoid unnecessary work.
These changes aim to reduce IO/CPU during frequent matching operations and produce more accurate/efficient matching for URNs and local models.
