Repairs the defect the independent closeout evaluator found when refuting the first baseline campaign (see PR #13's hold comment).

  • --settings '{"enabledPlugins":[]}' was schema-invalid (array vs object map) and silently disabled nothing — all three none rows ran with user plugins (incl. lcd) loaded.
  • Runner now builds {"enabledPlugins":{"<plugin>":false,…}} from the operator's real settings; fail-closed on unparseable settings or missing jq.
  • New tests assert the model call's actual argv via a recording stub (no --plugin-dir in baseline; disable map present in both arms) — replacing the printed-plan string checks the evaluator flagged.
  • 0.17.0 → 0.17.1 lockstep bump. Suite 12/12; golden untouched.

Campaign re-run under verified isolation follows; PR #13 will be updated with clean rows.

…uator findings)

Argv-recording stub replaces the model CLI: baseline leg must carry no --plugin-dir and a
schema-valid enabledPlugins OBJECT map disabling every user-enabled plugin; plugin arm must
carry --plugin-dir plus the same disable map; unparseable user settings fail closed.
Currently red: the runner passes the inert '{"enabledPlugins":[]}'.
