Restructure into a single PlatformIO project with nano and esp32 targets
- Shared BROSE9323 driver in lib/, ESPSERIAL selected via build_flags - Nano firmware in src/nano, ESP32 firmware in src/esp32 - Move WiFi/MQTT credentials to gitignored secrets.h (template provided) - Pin home-assistant-integration to 2.1.0 from the registry - Add esp32_usb environment for first flash / recovery - Add READMEs and CLAUDE.md Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
