  # Performs the following steps:
  # - Checks out the repository.
  # - Sets up PHP.
  # - Configures caching for PHPCS scans.
  # - Installs Composer dependencies.
  # - Make Composer packages available globally.
  # - Runs PHPCS on the full codebase (warnings excluded).
  # - Generate a report for displaying issues as pull request annotations.
  # - Runs PHPCS on the `tests` directory without (warnings included).
  # - Generate a report for displaying `test` directory issues as pull request annotations.
  # - Ensures version-controlled files are not modified or deleted.
