3-way merge of amnezia-vpn/amneziawg-go (AWG2, I1-I5 CPS + S4 keepalive) into sagernet/wireguard-go@506b763185 (the base sing-box uses). Keeps sagernet's sing-box-compat additions (Send offset contract, InputPacket, conn reserved/ control) and neutralizes the encapsulating headroom (MessageEncapsulatingTransportSize=0) so obfuscation composes cleanly. Obfuscation lives in device/ (obf*.go, magic-header.go new files + send/receive/device/uapi grafts); conn/tun/ipc kept pure sagernet. LIVE-VALIDATED: handshake + keepalive + traffic against a real AmneziaWG 2.0 server.
