重构项目文件结构并重命名根目录

✨ 新功能:
- 重新组织项目文件结构，采用模块化架构
- 重命名根目录: test1 → Bitcoin-Monitoring
- 更新Bundle标识符: com.mark.test1 → com.mark.bitcoin-monitoring

🔧 技术改进:
- Core/: 核心应用逻辑 (BitcoinMonitoringApp, MenuBarManager)
- Managers/: 业务逻辑管理器 (AppSettings, PriceManager, PriceService)
- Models/: 数据模型 (CryptoSymbol, RefreshInterval, BTCPriceResponse)
- Views/: SwiftUI视图组件 (PreferencesWindowView, AboutWindowView)
- Windows/: 窗口管理 (PreferencesWindowManager)
- Resources/: 资源文件 (Assets, entitlements)

📝 文档更新:
- 更新CLAUDE.md中的项目架构说明
- 修正文件结构描述以反映新的组织方式

✅ 验证:
- 项目编译成功
- 所有路径引用正确更新
- Bundle标识符已更新
