v0.9.0

Every parameter the bus reports is now a sensor.

Parameter discovery returns everything each device knows about itself — 88 values on the air conditioning alone: measured temperatures, mains presence, error codes, firmware and hardware revisions, timer configuration. Until now only a handful were reachable.

• one sensor per parameter, per device
• parameters are keyed by the device that reported them, so the interface's copy of a topic no longer overwrites the appliance's
• addresses belonging to the same physical device are folded into one Home Assistant device (the interface here answers on three)
• temperatures that carry real readings are converted from tenths; raw sensor values are left as they are

Writes stay with the climate and light entities: the same surface exposes System.FactoryReset and DeviceManagement.Delete.
