Created AgentMetadataService for Kind:0 metadata publishing and integrated it into AgentRepository.create(). The service creates Kind:0 events with agent name and personality info, signs them with agent's private key, and publishes to configured relays. Agent creation won't fail if metadata publishing fails.
