Create an eval run (async)Creates a suite run from an existing `suiteId` (rerun) and/or inline `tests`, then **detaches execution and responds `202` immediately** with the `runId`. Validation and quota errors surface on this request; poll `GET /eval-runs/{runId}` for progress. The run appears live in the hosted UI Runs tab, tagged `source: "api"`.
A bare `suiteId` with no inline tests reruns the suite as configured. Per-organization concurrency is capped (default 2 concurrent runs); exceeding it returns `429` with `details.reason: "CONCURRENT_RUN_LIMIT"`.
