Add an abstract teardown() classmethod to BottleBackend — the inverse of setup(), surfaced as `./cli.py backend teardown [--backend=NAME]` (uninstall). Symmetric with setup: it prints the privileged commands / declarative config change to remove the host prerequisites. - firecracker: NixOS-aware — disable the flake module (or drop the import) and rebuild, or `firecracker-netpool.sh down` imperatively. - docker / macos-container: nothing to undo (no privileged host state); print a short note. Not called by the launch path or the test suite. Extends test_cli_backend for the new dispatch.

"""Host setup + status for the macOS Apple Container backend.
|
|
|
|
Like Docker, this backend needs no privileged network-pool provisioning
|
|
— it wants Apple's `container` CLI installed and its system service
|
|
running. `setup()` points at the install/`container system start` steps;
|
|
`status()` reports readiness. Reached via
|
|
`MacosContainerBottleBackend.setup` / `.status`, dispatched from the
|
|
generic `./cli.py backend {setup,status}`.
