- Add `useAppRelays` boolean option to AppConfig
- Define APP_RELAYS constant with default app relays:
- wss://relay.ditto.pub
- wss://relay.primal.net
- wss://relay.damus.io
- Update NostrProvider to use getEffectiveRelays() which merges
app relays with user relays when useAppRelays is true
- Redesign RelayListManager with two sections:
- App Relays: Read-only list with enable/disable toggle
- Your Relays: User's personal NIP-65 relay list (editable)
- User relays now stored separately from app relays in config
- Default config starts with empty user relays and useAppRelays=true
