v2.9.0

What's New

• Added Sleep Number Climate 360 / FlexFit support, including BLE discovery and control for supported SleepIQ beds.
• Added Juna Sleep / Linx Keeson JSON/A00A support covering Quest, Rewind, Restore, Relax, and LV variants.
• Expanded Keeson documentation and test coverage for the new JSON/A00A family.

Bug Fixes

• Fixed Keeson JSON auto-detection so A00A devices do not fall through to overlapping Sino/OKIN heuristics.
• Fixed Keeson JSON preset handling and now prefer write-with-response when devices advertise both write modes.
