+- [2026-07-01 20:41:24]
+- **执行原因**: 按任务清单继续完成结构树 054-057。
+- **执行过程**:
+    1. 新增 `StructureTreeNode.vue` 递归树节点组件。
+    2. 将结构树改为层级数据绑定，支持 children 递归渲染。
+    3. 增加展开/折叠按钮和箭头旋转状态。
+    4. 增加已配置、待审核、已禁用、未配置四类状态圆点。
+    5. 点击树节点后更新高亮，并滚动到预览区对应 `data-block-id` 元素。
+    6. 增加全局 `tree-flash` 动画用于预览区闪烁提示。
+    7. 执行前端构建和浏览器 DOM 检查。
+- **执行结果**: 完成任务 054-057，结构树支持递归展示、状态、折叠和预览定位。
