원인: SelfDestruct 영역 즉시 Destroy(gameObject) → ParticleSystem 영역 진행 영역 trail·glow particle 즉시 사라짐 → 발사 영역 영역 영역 매번 시각 cut → "뚝뚝 끊기는" 인식.

fix:
- _fadeOutStarted flag — 중복 호출 차단
- Collider2D·_debugBoxTransform disable — 판정 종료
- _speed = 0 — 이동 정지
- ParticleSystem.Stop(true, StopEmitting) — emission 정지·기존 particle 자연 fade
- Destroy(gameObject, 0.5f) — 0.5s 후 Destroy (기존 particle lifetime 영역 자연 fade 완료)
- FADE_START_RATIO 0.8 → 0.85 (sprite fadeout 영역 영역 영역·자연 영역 영역)
