- Introduced a new service plugin architecture in core.py to manage multiple services, including the packet capture service. - Updated the configuration file (config.ini.example) to include a new [Weather_Service] section for enabling weather forecasts and alerts, along with relevant settings. - Enhanced the base service plugin class to support optional configuration section names and service descriptions for better metadata management. - Improved the packet capture service with explicit configuration section and description for clarity.
