ci: cancel stale pull request workflow runs
The CI workflow groups runs by commit hash, so every push to a pull request starts a separate workflow run. Group pull request runs by pull request number and cancel runs superseded by a newer push, while keeping push events grouped by commit hash for the skip-if-redundant behavior.
