PrismChainStep<T extends Object> class

A single step in a PrismPromptChain.

prompt can reference the output of previous steps using named placeholders: {{step1.field}} or {{input.field}}.

parse extracts a typed value from the model's response, so the next step can reference it by the step's outputKey.
