Structured findings

OpenAI's strict JSON mode rejects optional properties, so the required-vs-optional split for the v1 schema is enforced at the provider boundary: severity, file, line, title, description, and suggestion are required; line_end, language, snippet are optional and prompt-driven. See ADR-0014 §1 for the full contract.
