Under PHP 8.4, an implicitly-nullable parameter (a non-nullable type with a `null` default) emits "Implicitly marking parameter as nullable is deprecated". Downloader's constructor declared `ClientInterface $client = null`, so it fires once per class compile on 8.4. Mark the parameter explicitly nullable. The property is already documented `@var ?ClientInterface`, so this only makes the signature match the intent; behaviour is unchanged.
