阴影（本修正的核心根因）：
- Shadow pass 光源正交写深度（2048 D32），Forward 采样比较；
写入与采样共用同一 lightSpace 矩阵，杜绝姿态/镜像不一致
- 修复：push constant range 64B→128B（原 Shadow pass 推 {lightVP,model}
超出 layout 声明范围 = UB，阴影中模型矩阵读到垃圾导致旋转错乱）
- 修复：ShadowFactor 缺少 NDC→UV 映射（*0.5+0.5），采样区域整体错位
- 修复：RG ShaderRead stage 位值直转（eFragment=0x10 在 PipelineStage2
是 TESSELLATION_CONTROL），改为逐位显式映射
- Camera perspective 深度重映射到 Vulkan [0,1]（公式与 ortho 不同：
M22=M22*0.5-0.5, M32*=0.5）；光源 ortho remap 用 M32=M32*0.5+0.5
引擎配套：
- TransformComponent 重构为 position/rotation/scale + Compose()
- Texture::CreateSolidColor / Model::CreatePlane 程序化资产
（两段式上传公共路径），AssetManager.CreatePlane 带缓存入口
- RG 新增 GetPhysicalView(h, slot)：按帧槽位把 RG 资源绑进外部描述符
（阴影图 per-slot 物理镜像各自绑定）
验证：validation 0 error 0 warning，阴影随实体旋转正确
