Description

PR #120 introduced gRPC support for diagram-based workflow builders. That feature does not help native Rust API users.

We should provide a generic service builder function that allows user to easily spawn services that implement the same functionality that the diagram workflow builder has. However we should consider whether we can make the input and output types generic so users can select a service definition at runtime and we can infer the input and output types, as well as whether it's unary or streaming.

Research direction

Start by reading PR #120 and the existing diagram-based gRPC support to understand the functionality native Rust API users need. Define the scope for a generic service builder, including service-definition selection, input and output type inference, and unary versus streaming behavior; done means native users can access the same functionality without diagram workflows.
