fix(review): pass Review Army checklists by path, run research alongside dispatch, always probe the design detector; state review-log invocation and statuses in the caller fixture

- review-army-perf-n-plus-one: the parent copied full checklists into agent
  prompts and ran web research before dispatch (290 s on a 12-line diff); 212 s now.
- review-design-lite: 5 of 6 captured trials reported the detector absent
  without probing; the probe is mandatory and its first line is reported, and
  the contract credits only fake-engine rule ids the checklist never names.
- review-exploratory-small-cli: the fixture never gave review-log's direct
  invocation or status vocabulary; the model ran it through bun and wrote
  status "blocked". The prompt states both and the validator rejects
  out-of-vocabulary review statuses.
Each case passed a focused paid run after repair.
