LANTERN P1 Group B: 5-Spark systems — Aoe/Hitscan dispatch + reel/zone/decoy

Aoe/Hitscan archetype dispatch in AbilityFireSystem (both-worlds cooldown;
server-only ecb.Instantiate — the client-never-instantiates invariant; ZoneEffect
vs DecoyTag chosen by prefab membership). Harpooner REEL as a homing state
(ReelState + ReelSystem re-aim the hit Husk's KnockbackState toward the caster's
live position each tick; EnemyAISystem stays sole Position writer), stamped by
ProjectileDamageSystem on a Reel-flag hit. ZonePulseSystem (enemy-only periodic
AoE, caster attribution, no friendly fire, Vortex pull, born-0 lazy-stamp).
Decoy aggro in EnemyAISystem + DecoySystem despawn. AbilityDefBlob gains
EffectFlags (Reel) + DurationTicks. +3 ZonePulseSystem EditMode tests (497 green).
