Add cell execution_state

Closes #169

[krassowski]

I think this makes sense, especially given that jupyterlab/jupyterlab#16431 moves in this direction.

I think that merging this one does not preclude #227 from being merged.

Can we standardize that allowed values are running (or executing) and idle?

I would like to avoid using busy here as "busy" represents a couple of sub-states (like executing, pending-input, queued). Of note jupyterlab/jupyterlab#16431 used running but it was not released yet so we are not bound to it.

Actually only "idle" is used in this PR. I will rebase it.

[krassowski]

Yes, what I meant is that we probably should have some place to store source of truth for the enum values, this does not have to be addressed in this PR but would be good to settle on something soon.

[krassowski]

I think this one is good to merge 🎉

[krassowski]

Shall we merge this?

[krassowski]

Hearing no objections I am going to merge this one :)

[krassowski]

I will publish 3.0.0a3 now to integrate this with JupyterLab and jupyter-server-nbmodel

[krassowski]

It looks like do not have sufficient rights to release (https://github.com/jupyter-server/jupyter_ydoc/actions/runs/10282910526/job/28455597267) @davidbrochart are you able to help here?

RuntimeError: Could not get user permission level, assuming user was not admin!

I opened follow-up #259

[davidbrochart]

@davidbrochart are you able to help here?

Sorry I'm off with a very limited access to Internet, I'll look at that in a week or so.

[krassowski]

No worries, I will try asking someone else on the server meeting tomorrow to get rights to release. Are you able to get a quick look at #259 so that I could release that in an alpha to unblock jupyterlab/jupyterlab#16651?

[davidbrochart]

Done, let me try and release 3.0.0a3.

[davidbrochart]

Looks like 3.0.0a3 is out, but yes you should ask for release rights (I don't think I can give them to you).
