How about adding a stepId for step event?

[postbird]

I am new with ag-ui-protocol, it's awesome. I am learning it now.

I am wondering , for the step event, for example StepStarted or StepFinished, why we do not adding a stepId for unique identified.

For example, there are several same steps for one agent-running event, the step names are may same, is this a properly existing scene?
