Bluetooth Magic, first level

" summary

Builds a Bluetooth Low Energy mushroom-garden demo using AndroidX Bluetooth LE (alpha), GATT services and UUIDs, advertising, scan filters, and read/write of GATT characteristics; permissions and Android 33+ limits matter. Server side opens a GATT server, advertises and serves reads/writes and works; the client side struggles—library is coroutine-first but alpha and breaks for client GATT so callbacks are needed to get reliable reads. Repository with working server and fragile client is provided.
