Code Review

This pull request improves the lifecycle and connection management in MultiModalDialog and OkHttpWebSocketClient by introducing graceful shutdown timeouts, immediate force-close capabilities, and proper cancellation of upstream streaming subscriptions. Feedback on the changes suggests restoring the interrupted status of the thread when catching InterruptedException in the stop method of MultiModalDialog to ensure correct thread pool behavior.

When catching InterruptedException, it is a best practice to restore the interrupted status of the thread by calling Thread.currentThread().interrupt(). Swallowing the exception without restoring the status can prevent calling threads or thread pools from responding correctly to shutdown or cancellation requests.

      } catch (InterruptedException e) {
        close();
        Thread.currentThread().interrupt();
      }
