Graph Coordinator Node

[rlcurrall]

I'm trying out Genkit and the Graph plugin to understand it's capabilities. One thing I'd like to be able to do is have a "coordinator" node in my graph that looks at the current state of the graph and decides which node to go to next. I can certainly implement this without needing the ability to list out all the available nodes, but I was wondering if there was a way to get a list of available nodes from within the handler for a node so that I could pass the current state along with the available nodes to an LLM and have it decide the next node to visit.

Definitely enjoying the DX of Genkit and the Graph plugin thus far ❤️
