Move frontend source code to HuangYuChuh/ComfyUI_Skills_OpenClaw-frontend
so that cloning the main repo no longer downloads 1.4M of frontend source.
Users only need the pre-built assets in ui/static/.
- Remove frontend/ directory (now lives in its own repo)
- Add scripts/update_frontend.sh to pull latest release assets
- Remove frontend CI job (handled by frontend repo)
- Move Gemfile/Gemfile.lock to docs/ and update serve_pages.sh
- Clean up .gitignore (remove stale paths and Manus files section)
