"""Launch flow for the macOS Apple Container backend — disabled (#385).

This backend launched a per-bottle companion container (the egress /
git-gate / supervise data plane) alongside the agent container, with the
agent's proxy env pointed at the companion's host-only IP. That
per-bottle-companion architecture was removed in the companion-container removal;
the macOS backend will be re-enabled once it grows the consolidated
per-host gateway the docker backend already uses.

Until then, launching a macOS bottle fails closed. `prepare` / `status`
/ cleanup still work.
