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.

"""`backend` CLI command — generic host setup/status across backends.
|
|
|
|
`./cli.py backend setup [--backend=NAME]` provisions (or points at how
|
|
to provision) the chosen backend's one-time host prerequisites.
|
|
`./cli.py backend status [--backend=NAME]` reports readiness.
|
|
`./cli.py backend teardown [--backend=NAME]` undoes setup (uninstall).
|
|
|
|
All dispatch to the backend's `setup()` / `status()` / `teardown()`
|
|
classmethods, so there are no backend-specific commands — swapping
|
|
backends is just a different `--backend` (or `$BOT_BOTTLE_BACKEND`, or
|
|
the host default).
