feat: 添加 pre-commit hooks 配置

- 安装 husky 和 lint-staged 用于 Git hooks 管理
- 配置 pre-commit 检查：ESLint、TypeScript、Prettier
- 添加 Prettier 代码格式化配置和插件
- 更新项目文档说明 pre-commit 工作流程
- 配置文件包括：
  - .husky/pre-commit: Git pre-commit hook 脚本
  - lint-staged.config.js: lint-staged 配置
  - frontend/.prettierrc: Prettier 配置
  - frontend/.prettierignore: Prettier 忽略文件

现在每次提交前会自动运行代码检查和格式化
