Adds the full voice pipeline: 14-byte binary frame header, ChaCha20-Poly1305 AEAD keyed from the TLS exporter, libopus encode/decode with FEC/PLC/DTX, an adaptive per-ssrc jitter buffer, a miniaudio capture/playback engine, an APM passthrough stub, and the UdpBinding/StreamAnnounce signaling chain wired through ConnSession/SessionRegistry into a new server-side SFU (MediaRelay) that decrypts and re-encrypts frames per channel member. Exit criterion verified: test_m2_voice — two headless clients relay 50 encrypted Opus frames through the server; ctest --preset m1-dev is 9/9 green. Also corrects protocol.md's UdpBinding diagram, which described the UDP-side binding packet as AEAD-sealed when it is in fact a plaintext bootstrap frame (separate from the TCP/TLS UdpBinding ack).
