feat: 新增任务管理功能及相关组件

- 将目标页面改为任务列表，支持任务的创建、完成和跳过功能
- 新增任务卡片和任务进度卡片组件，展示任务状态和进度
- 实现任务数据的获取和管理，集成Redux状态管理
- 更新API服务，支持任务相关的CRUD操作
- 编写任务管理功能实现文档，详细描述功能和组件架构

+## 核心功能特性
+
+### 任务状态管理
+- **pending**: 待开始 (To-do - 蓝色)

+- **completed**: 已完成 (Done - 紫色)
+- **overdue**: 已过期 (Overdue - 红色)
+- **skipped**: 已跳过 (Skipped - 灰色)
+
+### 进度追踪
+- 支持分步完成（如一天要喝8杯水，可以分8次上报）
+- 自动计算完成进度百分比
+- 当完成次数达到目标次数时自动标记为完成
+- 实时更新任务进度卡片
+
+### 数据流程
+1. **获取任务**: 页面加载 → 调用API → 更新Redux状态 → 渲染列表
+2. **完成任务**: 用户点击完成 → 调用API → 乐观更新 → 更新进度
+3. **跳过任务**: 用户点击跳过 → 调用API → 更新任务状态
+4. **创建目标**: 用户创建目标 → 系统自动生成任务 → 刷新任务列表
+5. **页面导航**: 任务页面 ↔ 目标管理页面
+6. **进度更新**: 任务状态变化 → 自动更新进度卡片
+
+## API接口对应
+
+| 功能 | API接口 | 实现状态 |
+|------|---------|----------|
+| 获取任务列表 | GET /goals/tasks | ✅ |
+| 获取特定目标任务 | GET /goals/:goalId/tasks | ✅ |
+| 完成任务 | POST /goals/tasks/:taskId/complete | ✅ |
+| 跳过任务 | POST /goals/tasks/:taskId/skip | ✅ |
+| 获取任务统计 | GET /goals/tasks/stats/overview | ✅ |
