nostr:npub1yaul8k059377u9lsu67de7y637w4jtgeuwcmh5n7788l6xnlnrgs3tvjmf this has migrated over to NIP-65, (but without full outbox support). Some relevant new files of this migration would be `UserRelayListManager.swift` and `NIP65.swift`.

We still use the legacy format as a fallback, but give preference to NIP-65 lists.
