feat: adding interruption functionality to interrupt graphs

[haarshitgarg]

I couldn't find a way to interrupt whatever the graph was doing from the outside. So, to handle that I think just a bool flag to interrupt it whenever required and a handler to get the state of the graph.

With lack of pause and resume anyone using it can handle pause/resume externally with the state they do receive.

@bsorrentino let me know what you think as this is not the solution to the issue #5 but this do help with the interruption which I was not able to do otherwise

Very smart solution in using exception to force interruption. It is not clear to me how to resume from interruption point

We can store the current state as it does with the handler and possibly the node information. Next pass we can just start with that node maybe with little modifications?

Yes, the problem is store interrupted node information, I'm starting to implement standard LangGraph approach using Checkpoints & Interruptions to acheive this

@bsorrentino, In exactly this location I think I can get back nodeId which is I think you are referring to. I have not checked the checkpoints & interruptions in detail though

HI @haarshitgarg thanks again for contribution. After your push I've preferred re-use the common approach proposed by official LangGraph main project.

Would be great have your feedbacks about it
