feat: 系统托盘 (#12)

* feat: 系统托盘

1. 添加系统托盘
2. 托盘添加切换供应商功能
3. 整理组件目录

* feat: 优化系统托盘菜单结构

- 扁平化Claude和Codex的菜单结构，直接将所有供应商添加到主菜单，简化用户交互。
- 添加无供应商时的提示信息，提升用户体验。
- 更新分隔符文本以增强可读性。

* feat: integrate Tailwind CSS and Lucide icons

- Added Tailwind CSS for styling and layout improvements.
- Integrated Lucide icons for enhanced UI elements.
- Updated project structure by removing unused CSS files and components.
- Refactored configuration files to support new styling and component structure.
- Introduced new components for managing providers with improved UI interactions.   

* fix: 修复类型声明和分隔符实现问题

- 修复 updateTrayMenu 返回类型不一致（Promise<void> -> Promise<boolean>）
- 添加缺失的 UnlistenFn 类型导入
- 使用 MenuBuilder.separator() 替代文本分隔符
