* feat: enhance analysis command with statistics option

Refactored the analysis command to support an enhanced statistics option, enabling users to opt-in for detailed performance metrics of the analysis process. This change introduces a more flexible approach to handling statistics, allowing for a clearer separation between the analysis output and performance metrics, thereby improving the usability and insights provided to the user.
