ioBroker Hannah Adapter

Bidirectional gRPC bridge between ioBroker and the Hannah voice assistant (v0.13.0, released 2025-06-05). Replaces the prior MQTT-based integration, solving retained-message and wildcard-subscription problems. Streams device states, presence, and text commands in real time; supports device discovery via ioBroker enums, extra state prefixes, notifications, and Blockly blocks. Requires ioBroker js-controller ≥ 5.0, Node.js ≥ 22, and a running Hannah Core instance on the default gRPC port 50051. Releases are irregular but frequent (7 versions in 2 months).
