- Fix indentation bug causing scenes device to not register - Use nonlocal tracking to prevent infinite reload loops on target/scene changes - Guard WS start/stop to avoid redundant connections - Parallel device brightness fetching via asyncio.gather - Route set_leds service to correct coordinator by source ID - Remove stale pattern cache, reuse single timeout object - Fix translations structure for light/select entities - Unregister service when last config entry unloaded Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
