- Add esp32_devkitc_esp32_procpu overlay and board conf for DRAM tuning - Add SOC_SERIES_ESP32 to BLE security encryption override in Kconfig - Add ESP32 HCI ordering include in CMakeLists.txt (reuses esp32c3 cmake) - Add CONFIG_LINKR_BLE_BRIDGE_PAIRING_GPIO_AUTH Kconfig option to make the GPIO pairing button check optional (default y, boards can set n) - Add ESP32-WROOM-32 documentation in HARDWARE.md (pin mapping, DRAM constraints, build instructions, feature diff vs ESP32-C3) Verified on ESP32-DevKitC: BLE advertising, pairing, WiFi STA, WebSocket bridge all functional.
- Move factory reset GPIO0 to GPIO27 (external jumper to GND) - Default PAIRING_GPIO_AUTH=n for WROOM-32 - Guard GPIO init with IS_ENABLED in ble_security.c - Generalize pairing denial log message

feat(boards): add ESP32-WROOM-32 (Xtensa) board support
Add ESP32-DevKitC (ESP32-WROOM-32) as an alternative BLE-to-UART bridge target.
Key changes:
CONFIG_LINKR_BLE_BRIDGE_PAIRING_GPIO_AUTHKconfig option (default on, boards can disable)IS_ENABLED()for open-pairing buildsPin mapping: UART2 GPIO16/17 (bridge), UART0 GPIO1/3 (console via CH340), LED GPIO2, pairing GPIO4, factory reset GPIO27
Build:
west build -b esp32_devkitc/esp32/procpu && west flash --runner esp32Tested: BLE advertising, pairing, WiFi STA, WebSocket bridge, LED, credential persistence all verified on ESP32-DevKitC hardware.
