What it does
A starter platform integration for STM32 microcontroller boards. The module has the same shape as deki-esp32-integration (a DekiPlugin_* entry that registers platform providers), but at this stage only registers a TimeProvider. Filesystem, memory, and HAL backends are not yet fleshed out.
If you want to target an STM32 board, this is the right place to extend. The ESP32 integration is the reference for what a production HAL implementation looks like in this engine. Pair it with the bus and peripheral modules appropriate to your hardware.
