Subject: [PATCH] feat: initiative par tirage de carte de tarot
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Override Combatant.getInitiativeRoll pour piocher
une carte du paquet de tarot au lieu de lancer 1d6.
- Chaque combatant tire une carte → valeur = initiative
- Les cartes vont à la défausse après usage
- Fallback sur 1d6 si le paquet n'est pas disponible
- globalThis.HamalronTarotDeckManager exposé pour l'override
