Upgraded firmware for Simone Giertz's Every Day Calendar that links an ATProto-powered ESP32, for sync with goals.garden 🌱
Switch ESP32 env to S3 with 4MB flash and USB-CDC
- Change board from adafruit_qtpy_esp32s2 to generic esp32-s3-devkitc-1
- Add USB-CDC build flags for serial output over USB
- Configure 4MB flash size for QT Py ESP32-S3 variant
- Change flash mode from qio to dio for compatibility
