Subject: feat: add HTML index page for browser viewing

Add a beautiful HTML landing page when visiting relay in browser:
- Shows all three protocol endpoints (gRPC, Connect, WebSocket)
- Lists supported NIPs (01, 09, 11)
- Displays relay features and info
- Responsive design with gradient styling
- Serves on GET requests (regular Accept header)
- NIP-11 still served for Accept: application/nostr+json
