"""Launch flow for the macOS Apple Container backend.

The backend is registered and its host primitives are implemented, but
full launch is intentionally blocked until the sidecar network
enforcement design is finished. Apple Container can publish ports and
create networks, but bot-bottle's Docker topology relies on an agent
container attached only to an internal network while the sidecar bundle
also has egress. The first runnable version must preserve that
no-direct-egress property.
