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). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
