Fix camera switching and Contacts/SMS activity routing across shared hosts. Integrate Marketplace installation and native standalone recovery tools, Bluetooth runtime packages and trusted certificates. Update English/French READMEs and the shared changelog with tested scope and remaining radio/audio/Bluetooth limitations. Preview17 remains the existing APK; no new native image is released. Validation: shared JavaScript and native Python tests; Android packaging and payload parity from an isolated publication checkout.
