-**Responses:**
-- Success responses include `{ "success": true }` and an HTTP 2xx status
-- Error responses return the appropriate HTTP status (400, 404, 409, 500) with an error message
-- Long-running operations (downloads, benchmarks, embeddings) return 201 or 202 with a job/benchmark ID for polling
