ImagineCooldownCalc class

Shared cooldown math for Battle-Imagine (and any multi-charge) skills, used by both the CooldownBar and the CombatMeter so their timing can’t drift. Two parts:

• EffectiveDuration — the real per-charge recharge: the wire duration (or valid_cd_time) reduced by cooldown reduction (every player has a flat ~10% default; gear/buffs add the cooldown-acceleration attrs 11960 skill / 11980 imagine). Haste (atk/cast speed) does NOT affect this.
• Update — a sequential-recharge simulator. The wire moves begin only ON CAST and never reports a live charge count, and after the first charge’s window expires it says nothing about the remaining charges still recharging. So we simulate: each cast (begin advances) spends one charge and re-anchors the soonest-charge window; charges then return one per perCharge; time-to-full counts down continuously.

One instance per consumer (it holds per-key recharge state). Unity-free and pure → unit-testable.
