Allow users to adjust task hierarchy and order by dragging TaskRow:

const newParentName = newParent?.name || 'Root'
const positionText = position === 'after' ? 'after target task' : 'as child of target task'
showMessage(`Task [${draggedTask.name}] moved from [${oldParentName}] to [${newParentName}] (${positionText})`, 'success')
// 2. Call backend API to save new task hierarchy
try {
await api.updateTaskHierarchy({
taskId: draggedTask.id,
targetTaskId: targetTask.id,
position: position,
oldParentId: oldParent?.id,
newParentId: newParent?.id,
})
} catch (error) {
console.error('Save task hierarchy failed:', error)
showMessage('Save failed, please refresh page', 'error')
}
// 3. Trigger other business logic (like updating related data, recording operation logs, etc.)
// ...
}
</script>
```
**Drag and Drop Sorting Notes**:
- **Enable Dragging**: Set `enable-task-row-move="true"` to enable task row dragging (default is `false`)
- **Dragging Algorithms** (automatically executed by component):
- **Algorithm 1 (Place After)**: When target task has no children, dragged task will be placed after target task (same level), `position='after'`
- **Algorithm 2 (As Child)**: When target task has children, dragged task will become first child of target task, `position='child'`
- **Visual Feedback**:
- Semi-transparent following element displayed while dragging
- Blue border hint shown when hovering over valid target tasks
- Tasks without children show blue bottom border
- Tasks with children show blue border on all sides
- **Auto Sync**: Component internally mutates `props.tasks` via object reference, automatically completing task move, `parentId` update, `children` array adjustment, and TaskList/Timeline synchronization
- **Event Listening (Optional)**:
- `task-row-moved` event is completely optional, only used for showing messages, calling API to save, recording logs, etc.
- No need to manually update `tasks.value`, component has automatically completed data synchronization
- **Event Parameters**:
- `draggedTask`: The dragged task
- `targetTask`: The target task
- `position`: Drop position ('after' or 'child')
- `oldParent`: Original parent task (null means root)
- `newParent`: New parent task (null means root)
- **Constraints**:
- Cannot drag onto itself
- Cannot drag onto its own child tasks (avoid circular reference)
- Milestones and milestone groups cannot be dragged

```
**拖拽排序说明**：
- **启用拖拽**：设置 `enable-task-row-move="true"` 启用任务行拖拽功能（默认为 `false`）
- **拖拽算法**（组件内部自动执行）：
- **算法1（放置在后面）**：当目标任务没有子任务时，被拖拽的任务会放置在目标任务之后（同级），`position='after'`
- **算法2（作为子任务）**：当目标任务有子任务时，被拖拽的任务会成为目标任务的第一个子任务，`position='child'`
- **视觉反馈**：
- 拖拽时会显示半透明的跟随元素
- 悬停在有效目标任务上时显示蓝色边框提示
- 无子任务的任务显示蓝色底部边框
- 有子任务的任务显示蓝色四周边框
- **自动同步**：组件内部通过对象引用直接修改 `props.tasks`，自动完成任务移动、`parentId` 更新、`children` 数组调整以及 TaskList/Timeline 同步
- **事件监听（可选）**：
- `task-row-moved` 事件为完全可选，仅用于显示提示、调用API保存、记录日志等额外处理
- 无需手动更新 `tasks.value`，组件已自动完成数据同步
- **事件参数**：
- `draggedTask`: 被拖拽的任务
- `targetTask`: 目标任务
- `position`: 放置位置（'after' 或 'child'）
- `oldParent`: 原父任务（null 表示根目录）
- `newParent`: 新父任务（null 表示根目录）
- **限制条件**：
- 不能拖拽到自己身上
- 不能拖拽到自己的子任务上（避免循环引用）
- 里程碑和里程碑分组不能被拖拽
### 里程碑管理 ### 里程碑管理
里程碑用于标记项目中的重要时间节点，如项目启动、阶段完成、产品发布等。组件提供了灵活的里程碑编辑配置，默认使用内置的 MilestoneDialog，也支持完全自定义编辑行为。 里程碑用于标记项目中的重要时间节点，如项目启动、阶段完成、产品发布等。组件提供了灵活的里程碑编辑配置，默认使用内置的 MilestoneDialog，也支持完全自定义编辑行为。
