VinF Hybrid Inference: infer expected inputs from prompt (exploration)

[erikeldridge]

Problem Statement

Vertex doesn't require callers to pre-specify expected input types. Could we make the hybrid API do the same?

Findings

We can infer the types, but I'm unsure the complexity is worth the cost.

I'm putting up thie PR only for discussion.
