/**
 * @aquienpz/sdk/expo — native multipart uploads for React Native / Expo.
 *
 * Wraps `@aquienpz/asset-uploader-expo`'s `UploadTask`, which delegates
 * the actual byte transfer to a native background session (URLSession
 * on iOS, WorkManager on Android). The upload survives:
 *   - JS thread freezing
 *   - App backgrounding
 *   - OS-initiated kill (low-memory, user swiping away)
 *   - Network blips (retries with backoff)
 *
 * Usage:
 *
 *   import { createExpoUploader, listResumableSessions } from "@aquienpz/sdk/expo";
 *
 *   const aq = new AquienpzClient({ ... });
 *
 *   // Resume any uploads from a prior app launch on boot.
 *   const resumable = await listResumableSessions();
 *   // ...show a banner offering to resume them
 *
 *   const upload = createExpoUploader(aq, {
 *     file: { uri: assetUri, mime: "video/mp4", name: "tour.mp4" },
 *   });
 *   upload.on("progress", ({ ratio }) => setProgress(ratio));
 *   const { assetId } = await upload.start();
 *   await aq.slots.bind("storefront.tour.video", { assetId, preset: "video" });
 *
 * Peer dep: `@aquienpz/asset-uploader-expo` (lazy — apps that don't
 * use the mobile SDK skip the install).
