PD: "Enemy 닿으면 Player 피해 (밟기는 X·통과)"

근본:
- 직전 commit adcb1ac에서 Player↔Enemy 충돌 검출 자체 폐기
- Player 피해 경로 부재 → 복원 필요·단 밟기는 X

fix (EnemyController.Update):
- _cachedPlayer 캐싱 (Tag·fallback)
- Player.IsGrounded && VisualBounds.Intersects(Player.Bounds)
  → !IsInvulnerable 시 Player.health.Decrement (i-frame 적용)
- 공중 (점프) 상태는 통과·밟기 판정 X·EnemyDeath·Bounce X

회귀 영역 X:
- Enemy 사망 경로: Player 공격(Projectile·AttackHitbox)만 정합
- Player ↔ Enemy IgnoreCollision Awake 적용 정합·물리 통과
- Enemy ↔ Enemy IgnoreLayerCollision·발판 통과·scale·patrol 정합
