feat: ImGui docking Editor + 显示链/帧同步/输入语义重构

- App/editor: Hierarchy/Inspector/Viewport/Stats 四面板 + DockBuilder 默认布局，main.cpp 瘦身为场景搭建与生命周期 - 显示链: Tonemap→PresentTarget 经 ImGui::Image 呈现（零色偏），backbuffer 仅承载 ImGui；Direct/Viewport 双显示模式 + 面板分辨率上报 - 帧首同步 BeginFrameSync: resize/vsync/尺寸/模式意图统一帧首落定（修描述符悬垂）；修复 vsync 意图未落 swapchain 导致的每帧重建交换链 - 输入: Editor 每帧判定键盘/鼠标归属（打字让位、Viewport hover/focus 放行、Fullscreen 全放行） - 材质: roughness 独立槽位 + 非 glTF 金属/粗糙贴图映射；透明队列 depthWrite=FALSE + translucent 独立 shader + scratch 清帧 - FBX: 非蒙皮网格烘焙节点链全局变换（Z-up 旋转/单位换算落顶点） - Hierarchy 行 ImGui ID 以 UUID 作用域（重名不冲突、改名不丢选中）
