Fix workflow triggers to resolve hanging status checks

- Make CI workflow run on all branches instead of just master/testci
- Add OpenMP installation to CI workflow for macOS compatibility
- Add simple test workflow to verify GitHub Actions are working

This should fix the 'Waiting for status to be reported' issue by ensuring
the expected CI workflow actually runs on feature branches.
