feat: amélioration scripts bash, scan réseau, fix cron, README

Browse Source 
- system_prompt: section scripts bash (commandes interdites, mosquitto_pub, bonnes pratiques)
- script.py: nettoyage guillemets échappés à la sauvegarde
- network.py: nouvelle action scan (nmap/arp-scan/arp fallback), auto-détection subnet
- cron.py: _get_current_crontab() évite d'écrire "(aucune sortie)" dans le crontab
- README créé
