Subject: [PATCH] Integrate Codecov for test coverage reporting

This commit introduces Codecov integration into the GitHub Actions workflow.

Key changes:
- Added `pytest-cov` to project dependencies.
- Modified the `run-tests.yml` workflow:
    - Adjusted `PYTHONPATH` for correct coverage path mapping.
    - Updated the `pytest` command to generate an XML coverage report (`coverage.xml`).
    - Added a new step to upload the `coverage.xml` report to Codecov using `codecov/codecov-action@v4`.

This will enable tracking of test coverage over time and provide insights into code quality via Codecov.
