 * Builds a `Fetcher` that wraps the default `fetch` with a 16 MiB byte cap
 * on streamed response bodies. The wrapped `Response.body` exposes a
 * `ReadableStream` whose chunks flow through `createSseByteGuard`, so the
 * SDK's internal SSE parser (`EventStream` in
 * `@mistralai/mistralai/lib/event-streams.ts`) reads exactly as it would on
 * an unbounded body — but bounded.
 *
 * Bodyless responses (no `body` or no `getReader`) are returned unchanged so
 * the SDK's error-path `res.arrayBuffer()` call still works.
