Add a frozen ProxyPlan dataclass to pipelock.py (currently one field:
yaml_path; kept as a class so future proxy-level state has a home).
- prepare_proxy(spec, stage_dir) now returns pipelock.ProxyPlan
instead of a raw Path.
- DockerBottlePlan replaces pipelock_yaml_path + pipelock_yaml_filename
with a single proxy: ProxyPlan field.
- launch reads plan.proxy.yaml_path.parent / .name when calling
pipelock_start. Eventually pipelock_start should just take a Path
but that's a separate change.
