Documents the relay TLS identity bug (cert regenerates on restart
because server_config() creates a new keypair every time, ignoring
the persisted Ed25519 seed) and the full federation design:
- YAML config with mutual peer trust (url + fingerprint)
- QUIC connections between peers, fingerprint verification
- Room bridging: media forwarding for shared room names
- Merged participant presence across relays
- Helpful log message for unconfigured peer connection attempts
- No transcoding, no re-encryption, no central coordinator
