Sub Issue: Network Status Monitoring Implementation in runtime Directory

Background

This sub issue is based on Issue #113: Support online/offline network status monitoring.

Implementation Requirements

• Implement network status monitoring capabilities within the runtime directory of the project.
• For Android, leverage platform APIs such as ConnectivityManager to listen for online/offline network status changes and dispatch corresponding events (e.g., online, offline).
• For macOS, use platform capabilities such as SCNetworkReachabilitySetCallback to achieve similar online/offline event listening and notification.
• Ensure that the events can be triggered and handled in a manner consistent with the JSAR runtime event model.
• The implementation should allow higher-level APIs (such as window event listeners) to receive online/offline events according to platform changes.

• SCNetworkReachabilitySetCallback (macOS)

Additional Notes

• Focus on leveraging native platform capabilities for network status detection.
• Maintain modularity and separation of concerns within the runtime directory.
