Node-RED MQTT Broker (Aedes)

This Node-RED contribution provides an embedded MQTT broker directly within a Node-RED instance, eliminating the need for an external MQTT server like Mosquitto. Based on the actively maintained Aedes library (version 1.0 as of package version 1.x.x), it offers standard MQTT TCP and WebSocket support, including SSL/TLS, and various message persistence options (in-memory, MongoDB, file snapshotting). The current stable version is 1.2.0, with releases occurring as needed to track Aedes updates and Node-RED compatibility. It serves as a modern replacement for older Node-RED MQTT broker nodes that relied on the unmaintained Mosca library, distinguishing itself by its direct integration and modern backend.
