Extend MASQUE implementation to support TCP tunneling via standard HTTP/3 CONNECT method, in addition to existing UDP support via CONNECT-UDP: - Add StreamConn type for TCP data transfer over HTTP/3 stream body - Update handler to dispatch based on :protocol pseudo-header: - "connect-udp" for UDP (RFC 9298) - Empty/"HTTP/3.0" for TCP (RFC 9114) - Add handleConnectTCP() using bidirectional stream relay - Update connector to support both TCP and UDP networks - Add connectTCP() for standard CONNECT requests TCP uses :authority for target address and stream body for data. UDP uses path template and HTTP/3 datagrams for data.
