- Add get_model_urls() and download_model() to api.py and api_complete.py supporting all 14 discovered urlResult format keys (glb, obj, pbr maps, etc.) - Update generator.py to extract full urlResult dict instead of just modelUrl - Add CLI subcommands: formats (list available formats) and download (fetch by key) - Update reverse engineering docs with complete format key table and CLI examples
