When Bluetooth is disabled mid-scan on macOS, CoreBluetooth stops delivering advertisements, causing the Scan() function to hang indefinitely waiting for context cancellation. This update listens to the stateChanged event channel during scanning and exits the scan loop if the Bluetooth state changes to anything other than PoweredOn (e.g., PoweredOff).
