Research direction

Start by reviewing the referenced bash-track files, .github/workflows/pr.yml and .github/scripts/pr, to understand the proposed pattern for detecting relevant exercise changes. Compare that approach with this repository's CI configuration; done means pull requests run tests only for exercises whose relevant files changed.

Written by the indexing model from the issue text.

Description

I would like to reduce the friction in PRs that run all the exercise tests, although they do not interact with those files.

The bash track shows one way of doing so:
