wg_mtu_auto.py — Auto-detect egress IF, optionally probe Path MTU to one or more targets,
compute the correct WireGuard MTU, and apply it.

Examples:
  sudo ./main.py
  sudo ./main.py --force-egress-mtu 1452
  sudo ./main.py --pmtu-target 46.4.224.77 --pmtu-target 2a01:4f8:2201:4695::2
  sudo ./main.py --pmtu-target 46.4.224.77,2a01:4f8:2201:4695::2 --pmtu-policy min
  sudo ./main.py --prefer-wg-egress --auto-pmtu-from-wg
  ./main.py --dry-run
