Fix: Properly implement --list-cached-models with model-level information

- CoderAI cache: Shows individual GGUF files with sizes
- HuggingFace cache: Uses HF API (scan_cache_dir) to show model-level info, not individual files
- Shows model names, sizes, revision counts - not thousands of individual files
- Much more useful and readable output
