"""Launch a persistent cloud Linux container via the CLI.

    cua sb launch ubuntu:24.04 --json
    # parse name from JSON output, connect with SDK, run assertions
    cua sb delete <name>

Mirrors tests/integration/sandbox_sdk/test_linux_cloud_container.py but exercises the
CLI launch path and persistent state tracking instead of Sandbox.ephemeral().
Requires CUA_API_KEY environment variable.
