var statusCmd = &cobra.Command{
	Use:   "status",
	Short: "Show issue database overview",
	Long: `Show a quick snapshot of the issue database state.

This command provides a summary of issue counts by state (open, in-progress,
blocked, closed), ready work, and recent activity over the last 24 hours from git history.

Similar to how 'git status' shows working tree state, 'bd status' gives you
a quick overview of your issue database without needing multiple queries.

Use cases:
  - Quick project health check
  - Onboarding for new contributors
  - Integration with shell prompts or CI/CD
  - Daily standup reference

Examples:
  bd status                    # Show summary
  bd status --json             # JSON format output
