lx: graft AmneziaWG 2.0 obfuscation onto sagernet/wireguard-go

Browse source 
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.
