问题

<Image.PreviewGroup preview={false}> 不禁用预览：点击组内任意图片仍会弹出预览，且是无遮罩、动效错误的残缺弹层。单个 <Image preview={false}> 正常，仅 Group 场景失效。

antd 复现链接：https://codesandbox.io/p/sandbox/serene-galileo-dgq4pz?file=%2Findex.tsx%3A13%2C22

原因

PreviewGroup 用 preview && typeof preview === 'object' ? preview : {} 归并配置，把 false 与 null（antd 会把布尔 preview 归一成 null 再透传）吞成默认开启的空配置，onPreviewFromImage 又无门控，点击必弹。

修复

• PreviewGroup 将显式 false、null 视为禁用：onPreviewFromImage 直接返回，且不再渲染 <Preview> 面板；
• 禁用时同步重置非受控打开状态，「打开 → 禁用 → 再启用」不会无点击自动重现预览；该重置不触发 onOpenChange；
• 通过 PreviewGroupContext 广播 canPreview，禁用组内子图退化为普通图片：无 cover、无 button 语义、不注册预览条目，点击穿透给用户 onClick；
• 下游无需改动，antd 透传的 null 现按禁用处理。

Walkthrough

PreviewGroup 现在根据组级 preview 值控制图片预览交互和 Preview 渲染。preview 为 false 或 null 时，点击组内图片不会打开预览。

Changes

分组预览控制

Layer / File(s)	Summary
预览可用状态与触发流程 src/context.ts, src/PreviewGroup.tsx, src/Image.tsx, tests/previewGroup.test.tsx	PreviewGroupContextProps 新增 canPreview。当组级 preview 为 false 或 null 时，预览回调直接返回，已显示的预览会关闭，且不渲染 Preview。Image 根据分组上下文中的 canPreview 控制预览交互。测试覆盖禁用值和重新启用流程。
