Help on finding active maintainers for all/specific project(s)

### Expected Behavior

* Displays mentors for each eligible project for Codeheat.
* Displays most active mentor(s) for specific project, or for all projects.

The CLI likely fetches project data; start by examining the codebase structure to understand how it currently retrieves and displays information. Look for API calls or data sources related to CodeHeat projects and mentors. Determine where to add logic for filtering and ranking active maintainers, then implement the display in the CLI output format.
