Pull Request Overview

This PR adds support for operating on a subset of organizations rather than all organizations in an enterprise, along with adding progress flags and refactoring common file reading functionality. The key improvements enable more targeted promotion/demotion operations and better user experience through optional progress output.

• Added ability to filter organizations using --orgs or --orgs-file arguments
• Added --progress flags to show optional detailed progress information during operations
• Refactored file reading logic into a common read_lines utility function
