Great stuff! Would this also support the Langgraph.js client?

does this allow me to stream messages token by token, but load tool responses all at ones? I have a tool that uses an LLM but creates structured output, and i can't get it to NOT stream token by token

Instead of having to use yet another UI, as a dev, I prefer using Yacana as framework...
The UI is IMHO an admission of failure of the graph's code readability.
