fix(mpris): 修复 MPRIS 模块多项安全和性能问题

- 将 fix-sandbox.js 从 postinstall 移除，避免 npm install 时执行 sudo
- 修复 play/pause/stop 事件语义错误，不再全部映射到 togglePlay
- 缓存平台信息避免 sendSync 阻塞渲染进程
- 修复 cleanupAppShortcuts 中缺少 MPRIS 监听器清理导致的事件泄漏
- destroyMpris 中添加 IPC 监听器清理
- 清理冗余调试日志，安全加载 dbus-native 模块
- 添加 mpris-service 类型声明解决跨平台类型检查问题
