This commit bumps the wireguard-go dependency to incorporate changes to the packet memory model and the tun.Device.Read and conn.ReceiveFunc I/O interfaces. It updates their implementations accordingly. These changes improve throughput in all measured benchmarks and reduce peak RSS in six of eight cases. The two regressions will be addressed in a follow-up commit that reduces peak RSS below the baseline measured at1e69418. That work is kept separate to simplify review. The following throughput and peak RSS benchmarks were performed with iperf3 between two Intel i5-12400 nodes running Ubuntu 24.04 (Linux 6.8). The UDP benchmarks did not use UDP GSO on the sender, so they were roughly equivalent to single packet I/O through wireguard-go. TCP/1 signifies one TCP stream; TCP/128 signifies 128 parallel TCP streams.
