Implements a GitHub Actions CI/CD pipeline to protect the main branch by requiring all tests to pass before PRs can be merged. The workflow runs automated tests on every push and pull request to the main branch.

• Updated README.md with a workflow status badge and comprehensive branch protection setup instructions for maintainers
• Enhanced CONTRIBUTING.md with CI/CD documentation and updated PR checklist to include automated testing requirements
