fix(BT12-Dev Phase B): FX 재생 X — ParticleSystem 명시 Play + Collider 자식 분리 (PD 보고 2026-05-13)

원인 추정:
- PoisonSwampInstance 영역 BoxCollider2D·Rigidbody2D 영역 FX root 직접 부착 → ParticleSystem 영역 영향 가능
- Instantiate playOnAwake 정합·그러나 명시 Play() 호출 안전망 영역 누락

fix:
- PoisonSwampSpawner.Trigger — FX root 영역 GetComponentsInChildren<ParticleSystem>(true) 영역 명시 ps.Play(true)
- PoisonSwampInstance — BoxCollider2D·Rigidbody2D 영역 자식 GO 분리 (PoisonSwamp_Collider)·FX root 영역 visualRoot 보관·duration 종료 시 함께 Destroy
- PoisonedEnemyMarker.Tick — FX_Venom_Spray 영역 동일 ParticleSystem.Play(true) 명시 호출
- SpiritFireSpawner.Trigger — 동일 명시 Play(true) 호출
