Checkpoint 8

1. 统一调度收口为单点 Complete
2. 移除 Job 内部 Complete()，改为返回 JobHandle
3. 修复调度后 NativeList 安全冲突（关键）
  - 将 PrepareEnemyJobOutputBuffer/PrepareProjectileJobOutputBuffer/PrepareEnemySeparationJobBuffers 前置到 BuildInput
  - 互斥候选统计改为读取 _enemyJobInputs，不再在 Complete 前读取 _enemyJobOutputs
4. 新增 CP8 profiler markers
5. 新增回归用例（验证使用最新敌人移动结果构建碰撞候选）

+- [x] Checkpoint 7：Burst 策略落地与热路径约束
   - 热路径 Job 全部添加 `[BurstCompile]`，并在 Burst Inspector 确认已生效。
   - 清理 Job 内不兼容写法：托管分配、虚调用、LINQ、异常路径热调用。
   - 数学计算统一迁移到 `Unity.Mathematics`。
   - 完成标准：核心 Job 均由 Burst 编译，且无安全检查错误/降级回 Mono 的关键路径。

+- [x] Checkpoint 8：主线程职责收口与调度稳定
   - 明确主线程只做：输入采样、状态切换、UI 同步、实体显隐、最终写回。
   - 统一 `Schedule -> Dependency Combine -> Complete` 位置，防止隐式同步抖动。
   - 清理战斗帧中不必要的主线程循环（尤其逐实体逻辑）。
