2-relay test: 5.0s audio, RMS 4748, PASS. Full pipeline verified:
- Room correctly identified as global (hash matching works)
- Federation egress channel created and connected
- GlobalRoomActive signals exchanged between peers
- 300 packets (250 source + 50 FEC) forwarded via tagged datagrams
- Client B on relay B received full 5-second tone from client A on relay A
Added debug logging: is_global check, egress channel creation, per-peer
forwarding with active_rooms diagnostic when no match found. Also logs
egress packet count (first + every 250th).
Multi-hop propagation: GlobalRoomActive signals forwarded to other peers
so A→B→C chain knows about rooms across the full mesh.
