Improvements:

• Ensure consistency by adding newlines at the end of files.
• Consider using a single method for installing dependencies in CI and Dockerfile to avoid inconsistencies.
• Group related steps in CI for better readability and maintainability.
• Add comments where necessary to explain non-obvious steps, especially in scripts handling complex logic.
