KermitMqttLogger
Adapter that implements MqttLogger to send MQTT client logs to Kermit's Logger.
This allows the MQTTastic library logging to integrate with the app's logging infrastructure, including any configured log sinks (Crashlytics, Datadog, etc.).
The library's tag (e.g. "MqttClient", "MqttConnection") is forwarded as a structured Kermit tag so that Datadog receives it as an indexed attribute rather than freetext in the message body, enabling per-component filtering in log queries.
Note: The production log level should be set to MqttLogLevel.WARN (not INFO) to prevent the library's own INFO-level messages (which include endpoint addresses and topic strings) from reaching remote analytics sinks.
