P2: Improve CLI output and add verbose option

[ericanderson]

The current CLI output is too verbose and needs to be cleaned up for better user experience.

Tasks

• Reduce default output verbosity - show only essential information
• Improve formatting and styling of output messages
• Add -v/--verbose flag for detailed output
• Create clean, concise summary messages
• Use better formatting for lists and progress indicators
• Consider using colors/styles for better readability
• Ensure output is clear for both success and error cases
