refactor(bottles): absorb prepare/launch fns into DockerBottlePlatform
test / run tests/run_tests.py (pull_request) Successful in 14s

The module-level prepare_docker_bottle and launch_docker_bottle were
trivial delegations from the platform class. Move their bodies onto
DockerBottlePlatform.prepare and .launch directly. The launch method
keeps the @contextmanager decorator; isinstance narrows BottlePlan
to DockerBottlePlan at the entry point.

Internal helpers (_run_agent_container, _provision_container,
runsc_available) stay at module scope — they're stateless and don't
benefit from self.

No behavior change. Tests pass; dry-run output unchanged.

"""Docker bottle factory.
"""Docker bottle platform.
Two phases:
DockerBottlePlatform owns the two-phase factory:
prepare_docker_bottle(spec, stage_dir=...) -> DockerBottlePlan
.prepare(spec, stage_dir=...) -> DockerBottlePlan
Resolve names, validate host-side prerequisites, and write
scratch files (env_file, args_file, prompt, pipelock yaml) to
stage_dir. No Docker resources are created yet. Suitable to call
before the y/N preflight.
launch_docker_bottle(plan) -> ContextManager[Bottle]
.launch(plan) -> ContextManager[_DockerBottle]
Build the image, create networks, boot the pipelock sidecar,
launch the agent container (with `--runtime=runsc` iff the
daemon has gVisor registered), and copy prompt/skills/ssh/.git
