画布交互： - 滚轮缩放视口（2%~1600%），纯滚轮 10%/tick，Ctrl/Cmd+滚轮 3%/tick 精细控制 - 鼠标拖拽平移画布，Ctrl/Cmd+0 重置缩放 - 预览打开时锁定底层视口（previewActiveRef 事件穿透防护） - 预览内图片独立滚轮缩放 + 拖拽平移 + 缩放指示器 文件拖拽： - 画布缩略图/预览支持原生文件拖拽到外部应用（startDrag IPC） Bug 修复： - local-media:// 协议支持 UNC 网络路径 - passive event listener 报错：window 级原生 wheel listener 替代 React onWheel - Zustand v5 getState() 批处理旧值：改用 ref（currentZoomRef + setZoomRef）读写 主进程（electron/main.ts）： - 画布窗口 before-input-event 拦截 Chromium 页面缩放 - 新增 canvas-ipc.ts（startDrag、文件扫描等 IPC handler）
