feat(cli): add metrics status and reset commands

- Add --status flag to display metrics summary and exit
- Add --metrics-reset flag to reset metrics with confirmation
- Implement promptConfirmation() for safe destructive operations
- Add metricsReset to CliOptions interface
- Update help text with examples for new commands
- Show current metrics before reset to prevent accidental data loss
