feature: Change task's status indicator when waiting for user input

[Samigos]

When having multiple agents running at the same time, it's easy to miss a notification that an agent has questions. I think, instead of the orange/generating indicator, it should instead either show the blue/ready-but-unseen indicator, or a new one.

I'm willing to build myself - I don’t think it'll take much time - but I want to hear from you about the styling.

But it should be blue already hmm it's blue if the agent stopped + undread message. Orange is only when working.

Ok, then something’s off.
