Attack timing

Attack starts animator triggers and animation events invoke actual attack. Update observes InAttack, consumes resources on entry and stops on state exit/abort. Chain reset includes >.2s since previous attack. Resource skill discount is 33%*skill after equipment/status modifiers for stamina, then missing-health stamina return. Eitr cost reads the primary attack even for secondary calls; player consumption multiplies EitrRate/StaminaRate afterward.
