- warrior.tres: resource_type=RAGE, base_resource=100
- _gain_rage(): Wut aufbauen + Decay-Timer zurücksetzen
- _spend_rage(): Wut verbrauchen mit Prüfung (return false wenn zu wenig)
- _update_rage_decay(): Wut verfällt nach 5s außerhalb Kampf (10/s)
- take_damage(): +15 Wut wenn Krieger Treffer einsteckt
- Heavy Strike: +20 Wut beim Schaden austeilen
