files-sdk@2.4.1

c9f4105: softDelete() and versioning() can now be composed on one instance. Both plugins contributed a restore extension, so createFiles({ plugins: [softDelete(), versioning()] }) threw an extension collision at construction (#157). The two restores are now namespaced to match the names the gateway, FilesClient, and useFiles already use:
- versioning(): files.restore(key, versionId?) is now files.restoreVersion(key, versionId?).
- softDelete(): files.restore(key) is now files.restoreTrashed(key).
versioning() also gains an ignore option, a list of key prefixes that are never snapshotted. Pass the trash prefix when pairing the two plugins - versioning({ ignore: [".trash"] }) - otherwise a purge() (a real delete of the trash key) is snapshotted into .versions/.trash/…, a copy nothing lists and nothing reclaims. Place versioning() outermost so deletes are snapshotted before they’re trashed.
