add gatunad server and winforms client v1 (TCP-only)

Raw-Ethernet tunnel over ethertype 0x6969 to bypass WFP killswitches. Server (Rust, AF_PACKET + classic BPF) relays TCP to 127.0.0.1 services. Client (.NET 8 WinForms, SharpPcap/Npcap) discovers upstreams and exposes local loopback listeners. Wire protocol: 6-byte header, 7 frame types, MANIFEST with labeled upstreams. UDP types reserved, unimplemented.
