Both docker and smolmachines backends use bottle state helpers. Moving to bot_bottle/ makes the sharing explicit and removes the cross-backend dependency (smolmachines importing from ..docker). All callers updated: docker backend, smolmachines backend, cli modules, and tests.

"""Prepare step for the Docker bottle backend.
|
|
|
|
`resolve_plan` does all host-side resolution (image and container
|
|
names, env-file, prompt-file, proxy plan, runtime detection) and
|
|
returns a frozen DockerBottlePlan. No Docker resources are created;
|
|
the only side effects are scratch files under `stage_dir` and a probe
|
|
of `docker info`. Cross-backend host-side validation has already run
|
|
via the base class's `prepare` template before this is called.
