feat: HitProxy GPU 拾取 + UE 选中描边 + 编辑器拾取交互

- HitProxy 拾取：RG 管线渲染实体 id → host readback，点击帧
  PickEntity 精确命中；拾取按视觉几何（Model 联合包围球射线求交），
  与 Collider 解耦（UE/Unity 编辑器语义），命中打印实体名+碰撞体参数
- 选中描边（UE 语义）：SelectionMask pass（R8Unorm 完整投影轮廓，
  无深度测试透墙可见）→ Outline pass（边缘检测 + alpha 叠加，
  必须注册在 Tonemap 后）；edgeCut 贴视口边缘；widthPx=6 可调
- shader object 实证修复：VUID-08879 同程序 set layouts 超集一致、
  VUID-10065 push block 4×float 平铺、新 pass 析构销毁 VkShaderEXT
- RG：SideEffect() 保活"产出无 RG 内消费者"的 pass 链
- Editor：层次面板点击选中、Inspector 姿态编辑、Stats 面板拾取信息
- 相机 Update 改 const（姿态写入 Transform 引用，Camera 本身无状态变更）
