feat: adopt @unom/ui + add Projects section to the landing page

- Pull in @unom/ui (0.8.16) + @unom/style + peers; bump @unom/cms to 0.3.0.
- globals.css now provides the full semantic-token contract @unom/ui consumes
  (primary/accent/background/ring/radius-card/…), expressed with unom's violet
  brand + Inter/Ubuntu.
- Section wraps @unom/ui's Section (in-view animation orchestrator); PostCard,
  LatestPosts, and the hero use AnimatedCard/AnimatedText/AnimatedButton/Heading.
- lib/cms.ts moves to the multi-tenant model (tenant=unom), header/footer as
  per-tenant collections, + findProjects().
- New Projects section lists this tenant's projects on the landing page
  (soft-fails to hidden when empty). Starts with punktfunk.
