refactor: drop redundant single-parent fast path in _resolve_one_bottle

_fold_parents with one name returns after the first resolve; the
single-element branch was a verbatim copy of the general path.

+"""capability_apply — host-side orchestrator for capability-block
+remediation (PRD 0016).
+
+On approval of a capability-block proposal, the dashboard calls
+apply_capability_change(slug, new_dockerfile) which:
+
+  1. Snapshots the agent's transcript dir to
+     ~/.bot-bottle/state/<slug>/transcript/ (best-effort).
+  2. Pushes the agent's working tree via `git push` (best-effort —
+     no upstream / no commits / no git repo all skip with a log).
+  3. Writes the new Dockerfile to
+     ~/.bot-bottle/state/<slug>/Dockerfile (PRD 0016 Phase 1
+     state). The next `cli.py start <agent>` picks it up.
+  4. Force-removes the agent container + all sidecars + the
+     per-bottle networks. Idempotent — missing resources are not
+     errors.
+
+Returns (before, after) Dockerfile contents so the dashboard can
+record / render the diff. (capability-block has no audit log per
+PRD 0013 — the per-bottle Dockerfile state is its own record.)
+
+This is "fire-and-forget" from the agent's perspective: by the time
+the dashboard writes the response file the supervise sidecar is
+gone, so the agent's tool call connection drops without ever
+receiving the response. The replacement agent (next manual
+`cli.py start`) sees the new Dockerfile and starts from there.
+v1 does not auto-relaunch — see PRD 0016's capability-block return
+semantics open question.
