Outreach Generator

Generates structured partner outreach emails using Clean 50 and Jan 2026 playbooks for different audience segments. Accepts data_json as a JSON payload string with partner context (authoritative source of truth), segment as an audience segment enum, and topic as an email topic enum. Produces subject, body, and risk assessment fields tailored to the segment and topic. The worker must return only JSON that strictly validates against the system-provided structured output schema and must not emit markdown or code blocks.
