Initial commit: personal homepage with live Harbor registry

- Linktree-style homepage with photo, social links, and self-hosted
  services (container registry, Git server)
- Registry pages rendered on demand from Harbor via a live content
  collection, cached in memory (60s fresh, 10min stale-while-revalidate)
- Pinned registry images (PINNED_IMAGES) shown first with a star
- Node standalone server with security headers; self-contained server
  build so the Docker image ships no node_modules
- Gitea workflow building multi-arch images for Flux
