ci: add focused clone test workflow (UN-3770)

Adds a paths-scoped GitHub Actions workflow that runs the clone test
suite whenever clone code, its tests, or the dependency set changes.
Gives a fast, dedicated signal for the pagination page-following logic
in client._paginate — a silent-truncation regression there is worse
than a hard failure, so it must stay guarded on every clone change.

The full suite in test.yml still runs on every PR; this narrows the
trigger and the run to tests/clone/ for quicker feedback.
