Merge branch 'main' into auth

Brought in latest changes from main including:
- RSS feed implementation
- First letter edge case fixes
- Updated ranking formula

Resolved conflicts by:
- Combining .env.example variables from both branches
- Keeping auth version (3.0.0alpha)
- Preserving extended user schema from auth
- Keeping onMount umami approach and adding RSS feed link
