Contributor guide

Research direction
Explore the repository structure, focusing on how tests are currently run (composer.json and any CI workflow files). Research the Infection PHP mutation testing tool and how it integrates with PHPUnit. Identify the test suite and run it to establish a baseline. Then investigate how to add Infection to the development dependencies and configure it for this project. Also review the existing GitHub Actions workflow to see how to add a mutation testing job.
