- Introduced caching mechanisms for internet connectivity status in CommandManager to optimize performance and reduce redundant checks. - Updated command execution logic to skip commands requiring internet access when connectivity is unavailable, improving user experience and error handling. - Added synchronous and asynchronous utility functions for checking internet connectivity in utils.py. - Marked relevant commands (e.g., AlertCommand, AqiCommand, DadJokeCommand) as requiring internet access to ensure proper execution conditions.
