- Added explicit "none" scope handling so companion sends stay unscoped even when a default scope exists.
- Hardened packet and mesh security paths with multiple small fixes, including validation/handling updates in Packet.cpp and Mesh.cpp.
- Fixed small BLE behavior issues in companion message handling.
- Fixed an SX126x native driver race condition (via Zephyr patch update) to improve radio stability under concurrent events.
- Increased LoRa preamble settings to align behavior with vanilla baseline. (increased to 32)
