Adds Images/NucleoL476FW — a minimal RTE-compatible base firmware image for the ST Nucleo-L476RG (Cortex-M4F @ 80 MHz). It follows the same contracts as Gen6FW (RTE_EMIT markers, platform_api, STM32CubeMX CMake target) so NodeGUI graphs can be emitted and built without the full OpenVVVF hardware. Includes: - TIM1 center-aligned 3-phase complementary PWM at 10 kHz with 1 us DT - tim_isr + app_loop timing domains - baseline_graph.json proving codegen end-to-end (60/35/85% duties) - Build/flash/emit PowerShell scripts - Vendored CMSIS + STM32L4 HAL subset - SPI2 pins reserved for future FPGA join This is a lab/validation target, not a production inverter image. Sensor, telemetry, and safety paths are stubbed. Co-authored-by: Cursor <cursoragent@cursor.com>
