refactor(EnemyManager): 性能优化与并发安全修复

- EnemyRegistry: 移除List冗余存储, Register/Remove从O(n)→O(1)
- 增加PruneInvalidEntries显式清理接口, 消除TryGet副作用
- Remove增加不存在告警, 防重复减成负数
- 增加CTS取消飞行中的异步生成, 关卡切换时取消+重建
- ClearEnemies先快照再遍历, 防Hide回调修改集合抛异常
- entityId去掉取模复用, 直接自增保证唯一
- Enemy EntityGroup调优: Capacity→10000, ReleaseInterval→30, ExpireTime→120
