"""Launch a persistent local Android VM via the CLI.

    cua sb launch android:14 --local --json
    # parse name from JSON output, connect with SDK, run assertions
    cua sb delete <name> --local

Mirrors tests/integration/sandbox_sdk/test_android_local_vm.py but exercises the CLI
launch path and persistent state tracking instead of Sandbox.ephemeral().
Requires Android SDK (emulator + adb) to be installed.
