Automatic relay discovery over Nostr + call-to-action

Relay operators announce their relay with -announcerelay=host:port; every node
discovers announced relays (kind 38502) and adds them to its failover list, so
volunteer relays join with no maintainer edit or approval. Anti-spam cap +
validation; relays are trustless (echan makes a bad relay unable to read/MITM).
