本次提交为大规模架构优化，主要内容包括： - 统一 ViewModel/服务层依赖注入为具名工厂接口，消除 IServiceProvider 和裸 Func 反模式，提升类型安全与可维护性。 - 大量 ViewModel 构造与服务注册切换为工厂接口，页面 ViewModel 以 Transient 注册，导航时实例化，避免主窗口构造时实例化全部页面。 - 首页、收藏、选股、告警、设置等页面及子 ViewModel 通过 IMarketServiceRegistry 按市场类型解析服务，移除对 IServiceProvider 的直接依赖。 - RAG、MarketMonitor、投资选择等依赖通过专用 Provider/Factory 延迟解析，打破循环依赖，提升并发与资源管理能力。 - 新增 ImageCaptionClientFactory，统一多模态 Caption 客户端创建与降级。 - BinanceWebSocketService 连接生命周期管理优化，所有操作串行化，防止并发重连导致资源泄漏，支持断线重试。 - 修复 NewsUpdateService、BinanceUserDataStreamService 等 Stop/Start/重连场景下的资源释放与并发安全问题。 - 通知服务支持多通知堆叠与自动下移，优化用户体验。 - 首页最近查看条支持滚轮横向滚动。 - KLineChartView 离开可视树时释放 WebView 资源，避免句柄泄漏。 - 价格预警服务初始化异常时显式通知用户。 - 清理所有无意义注释，仅保留函数级文档和晦涩逻辑说明，代码更简洁。 - 统一数据解析区域性问题，使用 InvariantCulture 解析小数。 - 优化 CoinGecko/CoinDesk 币种 ID 解析逻辑，减少不必要的 HTTP 请求。 - 异步方法补充 CancellationToken，数据库连接异步化并优化并发锁处理。 - 优化正则表达式，提升文本清洗准确性。 - 增强单元测试隔离性，调整依赖注入注册方式，提升测试健壮性。 - 其它细节：异常处理、资源释放、UI 线程切换、集合线程安全、日志目录创建等优化。
