Refactor: Remove background task management and related hooks

- Deleted `useBackgroundTasks.ts` hook and its associated logic for managing background tasks. - Removed `backgroundTaskManager.ts` service and all related task definitions and registrations. - Cleaned up `Podfile.lock` and `package.json` to remove unused dependencies related to background tasks. - Updated iOS project files to eliminate references to removed background task components. - Added new background fetch identifier in `Info.plist` for future use.

-#   Gradle start up script for POSIX generated by Gradle.
-#
-#   Important for running:
-#
-#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
-#       noncompliant, but you have some other compliant shell such as ksh or
-#       bash, then to run this script, type that shell name before the whole
-#       command line, like:
-#
-#           ksh Gradle
-#
-#       Busybox and similar reduced shells will NOT work, because this script
-#       requires all of these POSIX shell features:
-#         * functions;
-#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
-#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
-#         * compound commands having a testable exit status, especially «case»;
-#         * various built-in commands including «command», «set», and «ulimit».
-#
-#   Important for patching:
-#
-#   (2) This script targets any POSIX shell, so it avoids extensions provided
-#       by Bash, Ksh, etc; in particular arrays are avoided.
-#
-#       The "traditional" practice of packing multiple parameters into a
-#       space-separated string is a well documented source of bugs and security
-#       problems, so this is (mostly) avoided, by progressively accumulating
-#       options in "$@", and eventually passing that to Java.
-#
-#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
-#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
-#       see the in-line comments for details.
-#
-#       There are tweaks for specific operating systems such as AIX, CygWin,
-#       Darwin, MinGW, and NonStop.
-#
-#   (3) This script is generated from the Groovy template
-#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
-#       within the Gradle project.

-# 后台任务系统实现文档
-
-## 概述
-
-本项目已成功集成iOS后台任务支持，使用Expo官方的 `expo-task-manager` 和 `expo-background-task` 库。该系统提供了完整的后台任务管理功能，支持任务注册、执行、状态监控等。
-
-## 技术栈
-
- **expo-task-manager**: Expo官方后台任务管理库
- **expo-background-task**: Expo官方后台任务库
- **React Native**: 跨平台移动应用框架
- **TypeScript**: 类型安全的JavaScript超集
-
-## 文件结构
-
-```
-services/
-├── backgroundTaskManager.ts    # 后台任务管理器核心逻辑
-├── backgroundTasks.ts          # 示例任务定义
-hooks/
-├── useBackgroundTasks.ts       # 后台任务自定义Hook
-components/
-├── BackgroundTaskTest.tsx      # 后台任务测试组件
-```
-
-## 核心功能
-
-### 1. 后台任务管理器 (services/backgroundTaskManager.ts)
-
-#### 主要特性
- **单例模式**: 确保全局只有一个任务管理器实例
- **任务注册**: 支持注册自定义后台任务
- **状态管理**: 完整的任务状态跟踪和持久化
- **错误处理**: 完善的错误处理和日志记录
- **后台获取**: 自动注册后台获取任务
-
-#### 核心方法
-
-```typescript
-// 初始化后台任务管理器
-await backgroundTaskManager.initialize();
-
-// 注册自定义任务
-await backgroundTaskManager.registerTask({
-  id: 'my-task',
-  name: '我的任务',
-  handler: async (data) => {
-    // 您的任务逻辑
-    console.log('执行任务:', data);
-  },
-  options: {
-    minimumInterval: 300, // 5分钟最小间隔
-    stopOnTerminate: false,
-    startOnBoot: true,
-  }
-});
-
-// 手动执行任务
-await backgroundTaskManager.executeTask('my-task', { customData: 'value' });
-
-// 执行所有任务
-const results = await backgroundTaskManager.executeAllTasks();
-
-// 获取任务状态
-const status = backgroundTaskManager.getTaskStatus('my-task');
-```
-
-### 2. 自定义Hook (hooks/useBackgroundTasks.ts)
-
-#### 主要特性
- **状态管理**: 管理任务状态和初始化状态
- **自动初始化**: 组件挂载时自动初始化任务管理器
- **便捷接口**: 提供简化的任务操作方法
- **实时更新**: 任务状态实时更新
-
-#### 使用示例
-
-```typescript
-const {
-  isInitialized,
-  taskStatuses,
-  registeredTasks,
-  registerTask,
-  executeTask,
-  executeAllTasks,
-} = useBackgroundTasks();
-
-// 注册任务
-await registerTask({
-  id: 'data-sync',
-  name: '数据同步',
-  handler: async () => {
-    // 数据同步逻辑
-  }
-});
-
-// 执行任务
-await executeTask('data-sync');
-```
-
-### 3. 示例任务 (services/backgroundTasks.ts)
-
-#### 预定义任务类型
- **数据同步任务**: 同步用户数据、运动记录等
- **健康数据更新任务**: 更新步数、心率等健康数据
- **通知检查任务**: 检查是否需要发送通知
- **缓存清理任务**: 清理过期缓存文件
- **用户行为分析任务**: 分析用户使用模式
-
-#### 创建自定义任务
-
-```typescript
-import { createCustomTask } from '@/services/backgroundTasks';
-
-const myTask = createCustomTask(
-  'my-custom-task',
-  '我的自定义任务',
-  async (data) => {
-    // 您的任务逻辑
-    console.log('执行自定义任务:', data);
-  },
-  {
-    minimumInterval: 120, // 2分钟
-    stopOnTerminate: false,
-    startOnBoot: true,
-  }
-);
-```
-
-## 使用指南
-
-### 1. 基本使用
-
-```typescript
-import { useBackgroundTasks } from '@/hooks/useBackgroundTasks';
-import { createCustomTask } from '@/services/backgroundTasks';
-
-const MyComponent = () => {
-  const { registerTask, executeTask } = useBackgroundTasks();

-};
-```
-
-### 2. 任务状态监控
-
-```typescript
-const { taskStatuses, getTaskStatus } = useBackgroundTasks();
-
-// 获取特定任务状态
-const taskStatus = getTaskStatus('my-task');
-console.log('任务状态:', {
-  isRegistered: taskStatus?.isRegistered,
-  executionCount: taskStatus?.executionCount,
-  lastExecution: taskStatus?.lastExecution,
-  lastError: taskStatus?.lastError,
-});
-```
-
-### 3. 批量操作
-
-```typescript
-const { executeAllTasks, cleanupTaskStatuses } = useBackgroundTasks();
-
-// 执行所有任务
-const results = await executeAllTasks();
-console.log('执行结果:', results);
-
-// 清理过期任务状态
-await cleanupTaskStatuses();
-```
-
-## 配置说明
-
-### iOS配置
-
-在 `app.json` 中已配置后台模式：
-
-```json
-{
-  "expo": {
-    "ios": {
-      "infoPlist": {
-        "UIBackgroundModes": ["remote-notification"]
-      }
-    }
-  }
-}
-```
-
-### 后台获取配置
-
-系统自动配置后台获取任务，支持：
- 最小间隔时间设置
- 应用终止时继续运行
- 设备重启时自动启动
-
-## 最佳实践
-
-### 1. 任务设计原则
- **轻量级**: 后台任务应该快速执行，避免长时间运行
- **幂等性**: 任务应该可以重复执行而不产生副作用
- **错误处理**: 完善的错误处理和重试机制
- **资源管理**: 合理管理内存和网络资源
-
-### 2. 性能优化
- **最小间隔**: 根据任务重要性设置合适的最小间隔
- **批量处理**: 将多个小任务合并为一个大任务
- **缓存策略**: 合理使用缓存减少重复计算
-
-### 3. 用户体验
- **静默执行**: 后台任务应该静默执行，不打扰用户
- **状态反馈**: 通过UI显示任务执行状态
- **错误提示**: 在任务失败时提供友好的错误提示
-
-## 测试
-
-使用 `BackgroundTaskTest` 组件进行功能测试：
-
-```typescript
-import { BackgroundTaskTest } from '@/components/BackgroundTaskTest';
-
-// 在您的页面中使用
-<BackgroundTaskTest />
-```
-
-该组件提供：
- 任务注册和取消注册测试
- 任务执行测试
- 状态监控测试
- 后台获取状态测试
-
-## 注意事项
-
-1. **iOS限制**: iOS对后台任务有严格限制，系统会根据电池状态和用户使用模式调整执行频率
-2. **权限要求**: 某些后台任务可能需要特殊权限
-3. **调试模式**: 在开发模式下，后台任务行为可能与生产环境不同
-4. **网络状态**: 后台任务执行时需要考虑网络状态变化
-
-## 故障排除
-
-### 常见问题
-
-1. **任务不执行**: 检查iOS后台模式配置和任务注册状态
-2. **执行频率低**: 系统会根据电池状态自动调整，这是正常行为
-3. **任务被终止**: 检查任务执行时间，避免长时间运行
-
-### 调试技巧
-
-1. 使用 `console.log` 记录任务执行状态
-2. 检查任务状态和错误信息
-3. 使用Xcode查看后台任务日志
-4. 测试不同的最小间隔设置
