Method coerce_to_schema

core/src/tools/task.rs:622–646

Coerce a step's free-text output into a JSON object validated against `schema`, reusing the structured-output machinery (Tool mode — the most portable across providers, with built-in repair). This is one extra LLM call beyond the step's own run.
