"""
Tests unitaires du TaskPlanner (planificateur MACRO).

Vérifie :
1. La compréhension d'ordres simples (understand)
2. Le matching de workflows par description sémantique
3. La détection de boucles et l'extraction de paramètres
4. La conversion étapes → actions JSON (format correct)
5. L'extraction de descriptions de session

Toutes les réponses gemma4 sont mockées pour la reproductibilité.
