- Add HAAvailabilityConfig for per-entity availability_topic and payloads - Defer discovery until MQTT connected; publish availability after discovery - HASensor/HANumber: optional suggested_display_precision in discovery - HASerializer/HADictionary: extend for new keys; update device types and mocks - Docs and examples reflect availability and precision usage - Tests updated for discovery and availability behavior - Ignore .cursor/ in repo root
