- Refactor __init__.py: extract run_source_search and execute_search_with_fallback helpers to eliminate duplicated progress-tracking, logging, and error-handling patterns across local, HuggingFace, CivitAI, CivArchive, and LoRA archive source search tasks; also fix URN variable shadowing in CivitAI/CivArchive - Update metadata/huggingface-author-index.json with refreshed Comfy-Org author index (new repos and model entries)
