v0.1.36: Add dark theme, fix BLE scanning, improve responsive design\n\n- Fixed BLE scanning RSSI error that caused 'BLEDevice' object has no attribute 'rssi'\n- Implemented complete dark theme with CSS variables and system preference support\n- Added responsive design with mobile-first breakpoints (768px, 1024px, 1440px)\n- Added theme toggle with local storage persistence\n- Improved BLE error handling and user guidance\n- Enhanced pairing function documentation to clarify BLE vs Classic Bluetooth\n- Updated version to 0.1.36 in config.yaml and api.py\n\nGenerated by Mistral Vibe.\nCo-Authored-By: Mistral Vibe <vibe@mistral.ai>
