Chat

Chat endpoint (PUBLIC — no JWT, uses X-API-Key). Returns RAG-generated answer with source documents. Errors: 401 (invalid/missing API key), 422 (invalid question), 503 (OpenAI unavailable). Honors the optional `Idempotency-Key` header: a retry within 24h replays the original response instead of re-running the LLM pipeline.
