 * Local filesystem implementation of StorageBackend.
 *
 * This combines the local implementations of all storage interfaces,
 * providing a complete backend for local e3 repositories.
 *
 * The `repo` parameter passed to each method is the path to the e3 repository directory.
 * This allows a single LocalStorage instance to be used for multiple repositories.
 *
 * @example
 * ```typescript
 * import { LocalStorage } from '@elaraai/e3-core';
 *
 * const storage = new LocalStorage();
 * const repo = '/path/to/repo';
 *
 * // Use the backend with storage-agnostic functions
 * const hash = await storage.objects.write(repo, data);
 * const packages = await storage.refs.packageList(repo);
 * ```
