ErrorService class
异常聚合服务 / Error aggregation service
接管 FlutterError.onError（保留默认红色报错行为），把每次异常按 类型 + 堆栈签名去重聚合，记录出现次数、首末次时间与一条完整堆栈样本， 形成独立的 Errors Tab，供开发者快速定位"同一处崩溃反复出现"的问题。 Hooks FlutterError.onError (keeping the default red error behavior), dedups each exception by type + stack signature, and records count, first/last seen time and a full stack sample — powering a dedicated Errors Tab to surface "the same crash happening repeatedly".
同时接管 PlatformDispatcher.onError：它能捕获 FlutterError.onError 漏掉的、发生在框架错误边界之外或平台通道回包中的异常（例如绘制/布局阶段 抛错后再次被框架捕获前的原始错误），避免这类崩溃完全不被聚合。 Also hooks PlatformDispatcher.onError, which catches errors that FlutterError.onError misses — those thrown outside the framework error boundary or from platform-channel replies — so they are aggregated too.
