保留 Tick 作为唯一入口，但让 SimulationWorld 只做 orchestration

- Tick 仍然是唯一仿真入口。SimulationWorld 顶层现在只保留全局开关、bridge 服务和生命周期入口，原来散落在类上的大部分跨域状态已经从 SimulationWorld 收口到新的 SimulationWorld.RuntimeModules。
- 新的 runtime modules 把状态按域分成了 SimulationStateStore、JobDataRuntimeState、CollisionPipelineRuntimeState、TargetSelectionRuntimeState，并通过同名代理把现有 partial 的调用面基本保持不变。
- CollisionPipeline 和 target-selection 的配置也一起下沉到了运行时模块。为了避免现有反射型测试立刻失效，保留了 _collisionQueryInputs 和 _areaCollisionRequests 这两个顶层兼容字段。
