refactor: move guest_home onto AgentProvisionPlan as source of truth
guest_home is now a field on AgentProvisionPlan (set by each provider's
provision_plan() method). BottlePlan.guest_home becomes a read-only
property delegating to agent_provision.guest_home so existing callers
(provision_git, provision_skills, provision_prompt) are unchanged.

Both resolve_plan.py files drop guest_home from the plan constructor
call; the local variable still exists as an intermediary for the
workspace_plan call that precedes agent_provision_plan.

"""smolmachines `_resolve_plan` (PRD 0023 chunks 2d + 4c).
Resolves the per-bottle docker subnet + bundle IP and assembles
the guest env. The agent's docker image build → smolmachine
pack pipeline runs in `launch.launch`, not here, so the
dashboard's preflight modal isn't garbled by docker-build output
before the operator has confirmed.
No VM bringup — that's `launch.launch`'s job."""
