root 4074e68715 experimental/windivert: P2.1+P2.2 with WinDivert NETWORK+SOCKET layers
WIP snapshot before pivot to sing-box+TUN. Reached:
- TCP redirect via streamdump pattern (swap+Outbound=0+reinject)
- SOCKET layer for SYN-stage flow detection (avoids FLOW Establish-too-late race)
- Lazy PID→name resolution (catches Update.exe inside procscan tick)
- UDP forward via SOCKS5 UDP ASSOCIATE relay + manual reinject
- Result: chat works, voice times out (Discord IP discovery / RTC handshake fails)

Reason for pivot: WinDivert NAT-reinject pattern has subtle layer-3
semantics issues that DLL-injection / TUN-based proxies sidestep
entirely. Going with embedded sing-box + wintun as the engine —
proven path for Discord voice through SOCKS5.

root feda075dc4 internal/divert: IPv4+TCP packet parse + RewriteDst + checksums
Build / test (push) Failing after 29s
Build / build-windows (push) Has been skipped
Pure-Go RFC 791/793 checksum implementation. Mutates buffer in
place — no allocations on the hot path. Used by the redirect layer
to NAT-rewrite Discord packets to 127.0.0.1:listener_port before
reinjecting via WinDivertSend.

UDP support deferred to P2.2.
