feat: improved the NDE check and throw a validation error

This implements a much strong check for nondeterminstic
errors in the workflow. Temporal's replay functionality
fails when it's not determinstic, so one big selling point
of Zigflow is to make a non-determinstic workflow impossible
(or, at least, very hard).
