The lint job installs ruff unpinned (pip install ruff), which reached 0.15.22
and, under preview = true, promoted the rule-codes-in-selectors diagnostic that
rejects rule codes like E501/S101 in lint.ignore. This project was the only one
with preview enabled. Dropping preview keeps the code-based selectors valid on
every ruff version in play (0.15.1 pre-commit pin, 0.15.7, 0.15.22 CI) and
aligns it with the other Python projects. No rule coverage change.
