Checkpoint 7

1. Job 通道数据结构改为 Unity.Mathematics 类型（float3/quaternion），并保留 Simulation 主数据结构不变。
2. 更新了通道边界转换函数：进入 Job 通道时转为数学类型，回写 Simulation 时转回 Vector3/Quaternion。
3. 敌人 Job 热路径去掉 Vector3/Quaternion 中间态，核心执行统一 math.* + float3/quaternion。
4. 投射物移动 Job 热路径同样统一为数学类型计算与输出。
5. 新增 Burst 开关 A/B 一致性回归测试（EditMode + PlayMode），并补了反射入口校验。
