	// DialContext opens the socket towards the relay. nil uses the net
	// package directly. It is called once per allocation with network "udp"
	// (or "tcp" when UDP is false) and the resolved relay host:port; a UDP
	// conn must be connected to that address, since it is driven as a
	// PacketConn whose every write goes to the relay. Socket buffers are
	// enlarged only when the returned conn is a *net.UDPConn. This is the
	// hook a sing-box outbound uses for detour and bind_interface.
