Initial commit — Agent HAL v1.0

Agent système complet remplaçant agent_debian :
- 20 skills : apt, systemd, cron, process, network, user, sysinfo,
  journal, container, shell, filesystem (enhanced), git, ssh,
  web_fetch, todo, script, mqtt_send, mqtt_subscribe, muc_send, agents_status
- filesystem : read avec numéros de lignes, edit, multiedit (style SHAI)
- git : status, log, diff, add, commit, push, pull, clone, branch, checkout
- ssh : exécution distante + SCP (password ou clé)
- web_fetch : GET/HEAD/POST avec nettoyage HTML
- todo : liste de tâches en mémoire
