Per user report 2026-05-14: 'Failed to execute text on Response: body stream
already read' при analyze с non-JSON error response.
apiFetchWithStatus делал .json() (consumes stream), потом .text() в catch
(FAILS — stream already consumed). Fetch API: body — ReadableStream,
consumable один раз.
Fix: read text() once → JSON.parse on string. На fail (HTML / non-JSON)
оборачиваем в {detail: rawText}. Никаких double-reads.
