[agent\_craft] Structured output with strict JSON schema suppresses reasoning and produces incorrect values

Use a two-stage pipeline. First generate free-form chain-of-thought with no schema constraint. Then feed that reasoning into a second call constrained to the required structured output.

Journey Context:
JSON mode constrains token generation and can suppress the intermediate reasoning needed to arrive at correct values. Splitting into reason-then-format stages lets each stage optimize for its own goal: the first thinks, the second complies. The extra call is cheaper than recovering from a wrong structured result caused by premature constraint.
