Add Comfy Registry publish files; update docs and clean repo
- Add pyproject.toml for Comfy Registry (publisher: comfyui-attic)
- Rewrite README to reflect tree-style file browser UI
- Fix api.py docstrings: route count (4 → 6), list_files error values
- ext.js: make cache_stats truly non-interactive (pointer-events:none),
show available MB instead of max, update on max_cache_mb change,
remove stale D3 comment
- Add .gitignore; untrack dev artifacts (api_spec.yaml, state.json,
docs/superpowers/)
