v1.2.2

Bug Fix

• Fix commands dropped during rapid zone on + temperature changes: When turning on a zone and quickly adjusting temperature, the await in async_refresh_if_stale() could yield control to the event loop, allowing the debounce timer to flush the command queue prematurely. Subsequent temperature commands would then be sent in a separate batch that could be rejected by the Overkiz API (device busy). Now skips refresh when commands are already pending, and compares against optimistic temperature for the skip-if-unchanged guard.
