fix(v0.1.9): détection IP/interface — filtre VPN WireGuard par flags kernel

- get_local_ip: construit d'abord la liste des IPs physiques (getifaddrs
  avec IFF_POINTOPOINT exclu + type=1 ARPHRD_ETHER requis), puis vérifie
  que l'IP choisie par le UDP-connect-trick en fait partie → évite de
  retourner une IP VPN même quand le trafic y est routé
- is_physical: remplace le filtrage par préfixe de nom par type kernel
  /sys/class/net/<iface>/type == 1 (Ethernet/WiFi) ; exclut WireGuard
  (type 65534), tunnels et autres interfaces virtuelles nommées librement
