Subject: [PATCH] feat: user nav dropdown in landing page + redirect to editor
 after OAuth login

- Google OAuth callback now redirects to /editor instead of landing page
- Landing page nav shows avatar, username and dropdown when logged in
  (My Projects, Open Editor, Sign out)
- Skeleton placeholder during checkSession so login button never flickers
