/**
 * IndexedDB-backed storage driver for structured browser storage.
 *
 * Unlike WebStorageDriver which serializes to JSON strings, IndexedDB
 * natively stores structured cloneable data, making it ideal for
 * complex objects, binary data, and larger datasets.
 *
 * @example
 *
 *     const driver = new IndexedDBDriver('my-app', 'settings');
 *     await driver.set('theme', { mode: 'dark', fontSize: 14 });
 *     const theme = await driver.get('theme');
