"""
水质参数反演分析系统 - 图形用户界面（重构版：纯壳模式）

WaterQualityGUI 只负责窗口框架（标题栏、菜单栏、状态栏、QTabWidget），
所有业务逻辑委托给独立的 Manager 类。

已实现的 Manager：
- PanelFactory           → 面板懒加载与生命周期
- PipelineExecutor       → Pipeline 执行/停止/回调（通过 EventBus 发布状态）
- WorkspaceInitializer   → 工作目录选择 + 自动回填（通过 EventBus 广播）
- LogManager             → 日志区 + 进度条（内部订阅 LogMessage/ProgressUpdate）
- ConfigManager          → 配置读写（new/load/save/get_current_config）
- DialogService          → 纯展示类弹窗（Pipeline状态/关于/AI设置）
- TrainingModeManager    → 训练模式切换（发布 TrainingModeChanged 事件）
