PR Description: Implement Optional rich.Progress Progress Bar in CLI

Summary of Changes

This pull request introduces an optional progress bar in the command-line interface using the rich.Progress library. Users can now enable a visual progress indicator for long-running tasks, enhancing the overall user experience.

How It Fixes the Issue

The implementation addresses issue #1628 by integrating the rich.Progress feature, allowing users to track the progress of operations in real-time. The progress bar can be toggled on or off based on user preference, providing flexibility while maintaining the existing functionality for those who prefer a simpler output.

Testing

I have tested the new progress bar feature across various scenarios to ensure it works as intended. This includes:

• Verifying that the progress bar displays correctly when enabled.
• Ensuring that the CLI functions as expected without the progress bar.
• Checking compatibility with different terminal environments.
