原因 / Cause:
五类飞剑实体共享 EntityDriveEx 的 alreadyHitEntity 列表；每次 AABB 扫描后的 removeAll 都对历史命中目标线性查询。

修复 / Fix:
将共享的 alreadyHitEntity 从 ArrayList 替换为 HashSet；保持候选列表、选择器、命中处理和生命周期逻辑原样。

性能收益 / Performance:
DriveEx 及其 Phantom、Flare、Hurricane、Lightning 子类扫描结果的历史命中排除由线性成员查找降为均摊常数时间。

兼容性 / Compatibility:
命中集合仅用于 clear、add、addAll 和 removeAll 成员判定，未被迭代或按顺序读取；候选实体仍按原始世界查询顺序处理。

验证 / Validation:
Java 8 下执行 Gradle 8.14.3 build --rerun-tasks --no-daemon --console=plain 成功（test 为 NO-SOURCE）。
