MCU_PIO: generic PIO driver with config-driven program loading, function-pointer init callbacks, blocking put, and DMA async put. ws2812.pio written from scratch — 800 kHz, 10 cycles/bit, side-set. HAL_LED: pixel buffer with intensity scaling, RGB byte order for RP2040-Zero WS2812 variant. SetColor immediately pushes the strip. APP_CLSW: rainbow HSV hue rotation on startup (auto-mode). Color commands (red/green/blue/off/rainbow) stop the rainbow and set the LED to a static color. Integer-only HSV-to-RGB conversion. CMake: added hardware_pio link and pico_generate_pio_header for ws2812.pio compilation. SYS_ECU init sequence updated.

# tiny build-time stat check on each file, which is well worth it for a

# small project where we add files often.
