Checkpoint 2 & Checkpoint 3

Checkpoint 2：Simulation 与 Job 数据通道打通
- 新增 Job 数据通道（Persistent NativeList）与 Simulation <-> NativeContainer 拷贝/回写流程
- 在生命周期接入通道管理（初始化、清空、集中释放）并接入 UseJobSimulation 分支
- 增强通道健壮性：失效容器自动重建，避免 EditMode 下 ObjectDisposedException
- 增加 UseJobSimulation 分支回归用例（EditMode/PlayMode 各 1 条）

Checkpoint 3：敌人移动与朝向 Job 化
- UseJobSimulation 分支正式切到 Job 路径
- 新增敌人移动/朝向 Job 实现（IJobParallelFor）：
	- Burst 版本 + 非 Burst 版本（受 UseBurstJobs 开关控制）
	- Job 计算移动、朝向、状态；主线程补做分离避让回补
- 扩展数据通道能力（为 Job 输出缓冲和投射物输出同步提供接口）
- 补充分支回归测试（开启 UseJobSimulation 后验证追踪与朝向）
