perf(enemy): 巡逻调试 Inspector 限频,消除每帧阻塞式 CanReach 掉帧

Browse Source 
上版 OnInspectorGUI 每帧 Repaint 且每帧调用 NavAgent.CanReach——该 API 会同步阻塞主线程
跑一次完整寻路(其文档自述"not optimal for performance"),选中敌人时每帧一次直接把帧率拖垮。

改为:刷新走 EditorApplication.update 定频(~5Hz)与游戏帧率解耦;CanReach 限频 ~2Hz 并缓存;
_maxSnapDistance 运行期不变只读一次缓存(不再每帧 new SerializedObject)。实测选中敌人 ~53fps 稳定无卡顿。
