+<!--
+  MES 物料分类树面板
+
+  功能：加载物料分类树 + 关键字过滤 + 点击节点通知父组件
+  用法：<MdItemTypeTree @node-click="handleTypeClick" />
+  说明：
+    - 组件 mount 后自动加载数据，也可通过 ref 调用 loadTree() 手动刷新
+    - 支持 toggle：点击已选中节点会取消选中（emit undefined）
+  Events:
+    nodeClick(data: MdItemTypeVO | undefined) — 点击树节点时触发；取消选中时为 undefined
+  Expose:
+    loadTree() — 手动刷新分类树
+    clearCurrent() — 清除当前选中节点高亮
