📄 Description

This is a stopgap until we figure out a good way to implement schema support in core - unclear if we should use Zod or if there's even a way to generate Zod schema from a StateDefinition.

Maybe the best long term thing is to even just use a type.

Also does a bit of housecleaning (removes Pregel as an input to the loop to match Python and remove the implicit circular dep)
