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

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

Mirrors tests/integration/sandbox_sdk/test_macos_local_vm.py but exercises the CLI
launch path and persistent state tracking instead of Sandbox.ephemeral().
Requires the Lume CLI on a macOS host.
