AI Summary: Evaluate the current panic handling in the Eclipse Paho MQTT Go client's filestore. Determine if the panics are appropriate for all failure scenarios (file not found, write failures, read failures) or if a more graceful error handling mechanism (e.g., logging errors and continuing) would be preferable. Consider the implications of changing the behavior, especially regarding message integrity and user experience. The goal is to improve the robustness and error reporting of the filestore.
