Subject: [PATCH] Fix langue et altitude relative dans SYSTEM_PROMPT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Ajout instruction explicite : message toujours en français
- Nouveau champ delta dans le schéma JSON : "monte de 5m" → delta=5,
  "descend de 3m" → delta=-3, null pour altitude absolue
- takeoff et altitude calculent target_alt = current_alt + delta
  quand delta est présent, sinon utilisent altitude absolue
