The previous <81 pin was directionally correct but too loose. pip resolves to setuptools 79.0.1 which still has the broken vendored jaraco/context.py:18 'from backports import tarfile' against anaconda's stub backports namespace on the dolent GitLab CI runners. setuptools 78.x is the latest version whose vendored jaraco doesn't include the backports.tarfile import. Verified locally: pip install 'setuptools<79' resolves to 78.x and the regtool import chain works.

Description
Follow-up to #100. The
setuptools<81pin we just landed is directionally correct but too loose: pip resolves tosetuptools 79.0.1(already in/home/gitlabci/.local/on dolent runners) which still has the broken vendoredjaraco/context.py:Anaconda's stub
backports/__init__.pydoesn't expose tarfile, so the import fails. Same failure as before the<81pin.Fix
Tighten the pin to
setuptools<79. This forces pip to install setuptools 78.x, whose vendored jaraco doesn't have thebackports.tarfileimport.Verification
Locally reproduced the failure on anaconda Python 3.11 and confirmed the import chain works with
setuptools<79:backports.tarfileimport?Test plan
