feat(maf): Phase 6 - migrate frontend workbench to tdesign-react and extract shared desensitize hook

+/**
+ * 区域级脱敏 Hook —— 把某个容器（DOM 子树）里的**所有文本节点**做脱敏，
+ * 用于「左/右侧面板 + 顶部标题」这类需要整片脱敏的区域：静态标题、动态内容、
+ * 嵌套子组件文本一并覆盖，无需逐串包 `desensitize()`（那样易漏、难维护）。
+ *
+ * 用法：`const ref = useDesensitizeSubtree<HTMLDivElement>(); <section ref={ref}>…</section>`。
+ *
+ * 设计要点：
+ *  - 只读改文本节点（display-only），不碰 `<input>/<textarea>` 的 value、不改 React 状态/回传值；
+ *  - `desensitize` 幂等（替换词不再命中词表），MutationObserver 重入安全；改写前先 disconnect 防自触发循环；
+ *  - 想在区域内**保留原文**（如内嵌沙箱/消息列表），给该子树根加 `data-no-desensitize` 属性即可跳过。
+ *
+ * 注意：**不要**用它包「消息列表正文」或「沙箱产物预览」——这两处按需求保持原文，
+ * 应作为独立容器、不挂本 Hook（智能体名称的脱敏单独在 MessageBubble 的 senderName 处理）。
+ *
+ * 该 hook 最初位于 `roundtable-planning/lib/use-desensitize-subtree.ts`，因其属于通用脱敏基建
+ * （被 MAF 会商、业务链条等多模块共享）现抽到中性 `@/lib` 位置。旧路径保留 re-export 以零改动兼容。

 /**
- * 区域级脱敏 Hook —— 把某个容器（DOM 子树）里的**所有文本节点**做脱敏，
- * 用于「左/右侧面板 + 顶部标题」这类需要整片脱敏的区域：静态标题、动态内容、
- * 嵌套子组件文本一并覆盖，无需逐串包 `desensitize()`（那样易漏、难维护）。
+ * 区域级脱敏 Hook —— re-export shim。
  *
- * 用法：`const ref = useDesensitizeSubtree<HTMLDivElement>(); <section ref={ref}>…</section>`。
+ * 实现已抽到中性共享位置 `@/lib/use-desensitize-subtree`（MAF 会商、业务链条等多模块共享）。
+ * 本文件保留导出，旧 roundtable-planning 消费者零改动、行为完全一致。
  *
- * 设计要点：
- *  - 只读改文本节点（display-only），不碰 `<input>/<textarea>` 的 value、不改 React 状态/回传值；
- *  - `desensitize` 幂等（替换词不再命中词表），MutationObserver 重入安全；改写前先 disconnect 防自触发循环；
- *  - 想在区域内**保留原文**（如内嵌沙箱/消息列表），给该子树根加 `data-no-desensitize` 属性即可跳过。
- *
- * 注意：**不要**用它包「消息列表正文」或「沙箱产物预览」——这两处按需求保持原文，
- * 应作为独立容器、不挂本 Hook（智能体名称的脱敏单独在 MessageBubble 的 senderName 处理）。
+ * 用法不变：`const ref = useDesensitizeSubtree<HTMLDivElement>(); <section ref={ref}>…</section>`。
