Constraint Mapper v2

Analyzes unstructured requirements or user stories to identify explicit constraints, trust boundaries, assumptions, and structural risks, returning a structured JSON object. Accepts userStory as a required string containing the raw requirements or intent text, and existing_constraints as an optional string describing current system invariants or context that must be respected. The worker must transform these inputs into an output that strictly validates against the system-provided structured output schema (auto-produced, not supplied here), with no extra keys and all types and enums respected.
