feat(backend): add teardown() to the contract; backend teardown
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).
