f218cd468b Add GPS, IMU, and barometer sensor suite to BLE bridge firmware 
RYS352A GPS on UART2 (GPIO5/6) with PPS interrupt (GPIO7),
MPU-9250 IMU and BMP388 barometer on shared I2C bus (GPIO8/9).
Sensor data exposed via dedicated BLE service with binary
notify characteristics alongside the existing NUS serial bridge.
Sensors degrade gracefully if not wired.

420a8e2039 Fix board ID and NimBLE 2.x API for ESP32-S3-N16R8 
- Use esp32-s3-devkitc1-n16r8 board (16MB flash, 8MB PSRAM OPI)
  instead of generic esp32-s3-devkitc-1 (8MB, no PSRAM)
- Remove setScanResponse() — NimBLE 2.x dropped this method
- Board definition handles PSRAM build flags automatically

Verified: clean boot, no PSRAM errors, BLE advertising as Travler-G2.

068f38d7eb Add ESP32-S3 BLE-to-RS422 bridge firmware for Carryout G2 
NimBLE-based Nordic UART Service (NUS) bridge on ESP32-S3-DevKitC-1.
Transparent passthrough: BLE client writes → UART1 TX → RS-422 → G2,
and G2 → RS-422 → UART1 RX → BLE notifications. USB serial serves as
debug monitor and fallback input.

Uses two MAX485 modules (one locked TX, one locked RX) with a SparkFun
BSS138 level converter for 3.3V/5V translation. Wiring schematic and
RJ-12 pinout documented in docs/ble-bridge-wiring.md.
