// The tool provides commands to query connected users and server status

// the server is running to monitor player activity.
//
// Usage:
//
//	usercheck <command> [options]
//	usercheck list                    # List all connected users
//	usercheck count                   # Count connected users
//	usercheck search -name "player"   # Search for a specific player
//	usercheck servers                 # Show server/channel status
//	usercheck history -name "player"  # Show player login history
