refactor: 解耦重构——还清四处架构债（对齐 UE/Unity 分层）

- SceneRenderer：场景→渲染数据翻译层（UE FSceneRenderer / Unity CullingResults
  模式），收口相机/灯光/光空间矩阵/双视图剔除，Renderer 只编排
- pass 对象化（Unity ScriptableRenderPass 模式）：8 个 pass lambda 拆为
  Passes::{Shadow,Forward,Bloom,Tonemap,ImGui,Present}，BuildGraph 超级函数消失；
  SceneGpu/FullscreenGpu 承接共享装配
- 中性 AssetRef（Core 层）：ECS 组件不再依赖 Assets 模块（Unity InstanceID 思路）
- IAssetUploader 接口：AssetManager 不感知 Vulkan 具体类，上传服务由渲染层
  VulkanAssetUploader 提供
- Renderer 公共 API 不变（App 层零改动），编译零错误 validation 零警告
