v2.9.1

What's New

• Added Sleep Number Climate 360 / FlexFit support.
• Added Sleep Number under-bed light and bed-presence support.
• Improved Sleep Number BamKey transport with framed fUzIoN blobs, notify-triggered readback, and the priming reads needed for presence polling.

Bug Fixes

• Fixed Sleep Number cancellation handling so HALT/STOP commands can still preempt blocked operations.
• Filtered placeholder BamKey notifications and readbacks instead of accepting them as real responses.
• Added CRC validation coverage and hardened the notify/readback transport flow.
