Add logging and ensure phpunit.xml exists to fix configuration errors

- Add logging steps to display directory structures for the repository, tooling folder, and test suite directory.
- Update .env file creation to set PLUGIN_DIR=${GITHUB_WORKSPACE} (repository root).
- Add a step to copy phpunit.xml.dist to phpunit.xml if phpunit.xml is missing.
- Ensure the workspace artifact includes hidden files.
- This provides detailed visibility of the environment and fixes the missing phpunit.xml error.
