feat(agent-scan-network): implémentation Phase 2 — découverte réseau

- Scan ping TCP multi-ports (sans root requis) - Lecture table ARP Linux (/proc/net/arp) - Détection 20 services par scan de ports TCP - Base OUI embarquée (~70 constructeurs courants) - API JSON locale Axum sur :9100 (GET /devices, GET /health) - Push automatique vers backend /api/v1/network - Enregistrement agent au démarrage - Config YAML (subnet 10.0.0.0/22, concurrence, timeouts) - ROADMAP Phase 1 et 2 marquées complètes Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
