Added
- @shaferllc/keel/ui — first-party design kit for Hono JSX views; the starter kits
  consume it instead of a local ui.ts.
- The saas kit grew social login (GitHub/Google), a background queue + scheduler, and
  a team-scoped REST API at /api/projects documented at /docs.
- keel-mcp package and the keeljs.com/install.sh curl path.

Fixed
- Team invites 500'd in the saas kit: invite() sends the email itself and needs
  teams.mail.from, which the kit never configured.
- The app kit's two-factor test matched a class-name prefix that had moved.
- The saas "personal team" test asserted an unescaped apostrophe.
