feat: configure NIP-05 verification for grimoire.rocks domain

Updates Grimoire member system to use grimoire.rocks domain and adds
proper NIP-05 verification infrastructure.

Changes:
- Update member NIP-05 identifiers from @grimoire.pro to @grimoire.rocks
- Create public/.well-known/nostr.json with member pubkey mappings
- Configure Vercel to serve nostr.json with proper headers:
  - Content-Type: application/json
  - Access-Control-Allow-Origin: * (required for NIP-05)
  - Cache-Control: public, max-age=3600
- Update rewrites to exclude .well-known paths from SPA routing

This enables NIP-05 verification for:
- _@grimoire.rocks → ce3cd5ba...
- verbiricha@grimoire.rocks → 7fa56f5d...
