feat: add relay.nostr.band as hardcoded relay

- Create HARDCODED_RELAYS constant with relay.nostr.band
- Always include hardcoded relays in relay pool
- Update computeRelaySet calls to use HARDCODED_RELAYS
- Ensures we can fetch events even if user has no relay list
- relay.nostr.band is a public searchable relay that indexes all events
