ci: run drift_check tests in validate.yml (#63)

Adds a test-drift-check job to validate.yml that installs pytest from
the new requirements-test.txt and runs pytest tests/ -v on every PR and
push to main.

The 9 tests in tests/test_required_workflows.py are pytest-discoverable
as-is (functions named test_*). No conversion needed. The test file adds
scripts/ to sys.path so no PYTHONPATH config is required.
