oskarvitaliiandClaude Opus 4.8 11f57a244d chore: make repo an Arduino collection with WeatherPredictor project
Flatten so the repo root is the Arduino sketchbook; the project lives in
WeatherPredictor/. Add a collection index README at the root and move the
detailed project README into WeatherPredictor/.
