/**
 * FileRestoreReader implements WalletStorageSyncReader to serve sync chunks
 * from a previously exported backup ZIP file during wallet restore.
 *
 * Usage:
 * 1. Unzip the backup file with fflate.unzip()
 * 2. Read and parse manifest.json
 * 3. Create FileRestoreReader with unzipped data and manifest
 * 4. Call storage.syncFromReader(identityKey, reader)
 * 5. Reader serves chunks sequentially via getSyncChunk()
 *
 * @example
 * ```typescript
 * import { unzip } from 'fflate';
 *
 * const zipData = new Uint8Array(await file.arrayBuffer());
 * const unzipped = await new Promise<Unzipped>((resolve, reject) => {
 *   unzip(zipData, (err, data) => err ? reject(err) : resolve(data));
 * });
 *
 * const manifest = JSON.parse(
 *   new TextDecoder().decode(unzipped['manifest.json'])
 * );
 *
 * const reader = new FileRestoreReader(unzipped, manifest);
 * await storage.syncFromReader(manifest.identityKey, reader);
 * ```
