Subject: [PATCH 6/6] Add test execution and failure reporting to build.yml

- Add 'Run tests' step using `make test` to run the full git test suite
- Add 'Print test failures' step using `ci/print-test-failures.sh` for
  clear failure output on GitHub Actions
- Add 'Upload failed tests' step to upload test artifacts on failure,
  conditioned on FAILED_TEST_ARTIFACTS being set by the print step
- Update upload-artifact action to v5 to match main.yml
