This pull request updates the code coverage upload process in the GitHub Actions workflow to use Codecov instead of the previous GitHub code quality action. The main change is to integrate with Codecov for uploading coverage reports, which may improve reporting and integration with external tools.

CI/CD and code coverage integration:

• Replaced the GitHub code quality coverage upload step with the Codecov upload action (codecov/codecov-action@v5) in .github/workflows/test.yml, and configured it to use the Codecov token secret.
