HitBox 新增 HitMode Single/Interval：Interval 用 Enter/Exit 跟踪占用 + Update 轮询，对停留目标按间隔重判，不再依赖 OnTriggerEnter 单次语义。BodyContactDamage 改用 Interval 模式，修复停留在接触判定内、无敌结束后不再受伤的 bug；FlyingEnemy 接触伤害加按目标间隔节流。ProjectileConfigSO 新增 MaxHits 默认 1 即命中即消失，Projectile 按命中预算回收，修掉默认无限穿透；弹反守卫避免反射后立即回收。 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
