# GitHub Actions CI workflow for rsync-deployments
# This workflow validates the action on every push and pull request by:
# - Running BATS tests for the entrypoint script
# - Validating the action.yml definition
# - Building and testing the Docker image
# - Checking file structure and permissions
# - Linting shell scripts
# - Running a final integration check
