- tcp.rs: Aura proto handshake + Session directly over TcpStream (TcpServer/
TcpClient/TcpConnection: PacketConnection), with an optional light HTTP/1.1
masquerade preamble. Fallback for UDP-blocking networks. (Full TLS-443 mimicry
is a documented follow-up.)
- dial.rs: TransportMode {Udp,Tcp,Quic}, Endpoints, DialConfig; client `dial()`
tries transports in order and hands over on failure/timeout; MultiServer binds
and accepts on every enabled transport at once (TCP/QUIC multi-client; UDP
single-peer-per-accept in v1).
- Tests: tcp loopback (plain + masquerade), dial handover (dead TCP -> UDP).
clippy/fmt clean.
