To: linux-bluetooth; +Cc: luiz.dentz, quic_mohamull, quic_hbandi, quic_anubhavg
From: Prathibha Madugonde <prathibha.madugonde@oss.qualcomm.com>
Add RAS packet formatting and notification support for CS reflector
Implement complete RAS data pipeline:
- Handle HCI CS subevent result/continuation events
- Serialize ranging/subevent headers per spec
- GATT notifications for real-time ranging data
