fix 1

1. 修复投射物闪避口径（使用 Value，与全局伤害逻辑一致）
  - 将 SimulationWorld 内投射物伤害计算改为直接复用 AIUtility.CalcDamageHP(...)。
  - 删除了 SimulationWorld 里那套重复且使用 dodgeStat.Percent 的私有计算函数，避免再次分叉。
2. 修复目标选择索引“重建过于激进”
  - 去掉了 Job Tick 末尾的“每帧强制 MarkDirty + Build”。
  - 改为在 Job 输出回写时，只有敌人 XZ 坐标发生变化才标记 dirty。
  - 空间索引构建条件改为“仅 dirty 时重建”，不再因跨帧自动重建。
