DirectlineStreaming: Errors on disconnect are written to console

When disconnecting a connection that has pending requests, the infra botframework-streaming package rejects all the requests with "Disconnect was called" error.

It looks like the botframework-directlinejs package writes this error to the console instead/in addition to emitting an error event to the application.

This bypasses our logging system, and should not be done by libraries.

I suspect the console log comes from here or from here.

There are other calls to console.warn and console.error in the library. They should be replaced where possible with proper error propagation.

先阅读 src/directLineStreaming.ts 中第 262 行和第 429 行附近的内容，然后检查 nodeWebSocketClient.ts 的拒绝行为。检查库中其他的 console.warn 和 console.error 调用；当断开连接错误及其他适用的失败通过应用程序错误路径传播，而不是直接写入控制台时，即表示完成。
