Bug: spirit toggle ON → Imperil intercepts → toggle OFF → never fires skill.
The 3-state flag for spirit burst worked, but debuffs (Imperil at step 6)
came before weapon skills (step 11) in the priority chain. Each time the
flag advanced past 1, Imperil fired instead of Rending Blow, consuming
the turn and causing spirit to toggle off without ever using the skill.
Fix: debuffs now check _spiritForSkill === 0 before firing. When spirit
burst is pending (flag >= 1), skip Imperil/Weaken so the weapon skills
section fires uninterrupted.
