Feature or enhancement

Proposal:

As @erlend-aasland and I have worked on adding type hints to Argument Clinic over the last few months, and applied various other modernisations to Tools/clinic/, running pyflakes on the code on a regular basis has caught numerous small bugs that periodically crept in due to a refactoring. Pyflakes has an extremely low number of false positives, so it would be great to have this run as part of CI to catch these issues before they're merged in.

Following #109161, we now run ruff in CI on the Lib/test/ directory, and ruff has implementations of all the pyflakes error codes. I propose that we add a CI check that runs the full set of pyflakes checks (via ruff) on Tools/clinic/.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
