lumalou: reconstructing Fisher-Price Lumalou BLE control

lumalou reconstructs local Bluetooth LE control of the Fisher-Price Lumalou bedtime device after its companion app was discontinued. Python and TypeScript implementations perform the MPID handshake with P-256 key exchange and AES-128-CTR framing, then control lights, audio, schedules and routines. The repository includes protocol documentation, shared test vectors and a browser client.
