Add NAT64 and vclient IPv6 support

NAT64 translates between IPv6 and IPv4, allowing IPv6-only clients to
reach IPv4 servers via ::ffff:x.x.x.x addresses. Includes TCP/UDP/ICMP
translation with full checksum recomputation.

vclient gains IPv6 support: TCP/UDP connections, DNS over IPv6, and
automatic IPv4→::ffff: conversion for IPv6-only clients (NAT64 path).

L3Hub adds SetDefaultRoute for packets that don't match any connected
prefix, needed for routing ::ffff: addresses to the NAT64 gateway.

End-to-end test verifies: IPv6 client → NAT64 → IPv4 HTTP server, and
IPv6 client → NAT64 → slirp → GitHub (real internet).
