Import the STM32F4 and STM32G4 CMSIS device headers from STMicroelectronics' dedicated RIM-tracked repositories. Keep only the F413 and G474 headers needed by the STM32 MCU foundation and record the unused upstream headers as RIM ignores.
Add the STM32 platform entry point, chip CMake files, bspMcu startup code, a software reset wrapper, and the STM32 unit-test presets. The platform reuses the shared CMSIS core from libs/3rdparty/cmsis instead of carrying a local copy.
Add STM32 BSP modules for clock, UART, GPIO, timer, ADC, and EEPROM, plus interrupt handling primitives and the ETL platform glue.

Add bxCAN and FDCAN device drivers with STM32 CAN tests. Add the bxCAN transceiver adapter and unit-test registration.
Add the FDCAN transceiver implementation and STM32 test coverage. Wire the FDCAN transceiver into the chip-family CMake selection.
Add the STM32 hard fault handler with RAM dump region and the IWDG watchdog driver. Add the G474RE safety manager sources and watchdog unit tests.

Add the NUCLEO-F413ZH reference application board: BSP configuration, board main with FreeRTOS and ThreadX variants, bxCAN CAN system, and the board presets.
Introduce two feature flags set by the STM32 board options: PLATFORM_SUPPORT_OBD_UDS_ADDRESSING selects 0x7E0/0x7E8 tester CAN IDs and logical address 0x0600, and PLATFORM_SUPPORT_PROGRAMMING_SESSION adds an application-level programming session. The BSW ProgrammingSession disables the UDS dispatcher on entry (bootloader handover), so the application session keeps the dispatcher alive and uses session index 0x02 to avoid matching PROGRAMMING_SESSION() in switchSession().
Add demo UDS services for the STM32 boards behind the PLATFORM_SUPPORT_UDS_DEMO_SERVICES board option: ECU reset, an in-memory DTC store with read/clear/control services, security access, VIN write, and demo routine control. The UDS dispatcher accepts functional requests when the demo services are enabled.
