chore(project): 初始化 React 项目并更新依赖配置

- 将项目从 Chrome 扩展模板迁移到 Create React App
- 移除原有的 Chrome 扩展相关文件(background.js、content.js、manifest.json)
- 删除旧的开发指南 DEVELOPMENT.md
- 更新 package-lock.json 以支持 React 开发环境
- 替换 .gitignore 文件内容为标准 React 项目忽略规则
- 移除所有原有的图标资源文件(images/*.png)
- 更新 README.md 为 Create React App 标准文档
- 添加 React、React DOM、React Router 等核心依赖
- 配置测试库(@testing-library)及相关工具
- 设置 web-vitals 性能监控依赖
