Enable stream-unzip under Python 3.14

[hagenw]

Removes the restriction to not install stream-unzip under Python 3.14, as it now simply works. I guess one of its dependencies was not working with Python 3.14 before.

Reviewer's Guide

Removes the Python 3.14 restriction for the stream-unzip dependency and makes ZIP archive extraction always use the streaming implementation when num_workers == 1, simplifying tests by assuming stream-unzip is always available.

    A[get_archive called] --> B{src_path ends with .zip?}

    D -- Yes --> F[Call _get_archive_streaming]
