robbond cf09a72739 feat(confidence-engine): add --variant hidden|visible to overview experiment helper for controlled A/B
- Helper now supports --variant visible which appends unresolved Open Questions
  as a separate NON-EVIDENCE section to the baseline prompt (built via production
  buildOverviewSynthesisPrompt)
- Default (--variant hidden, or no flag) remains production path
- No production code changed; apparatus-only extension
- Deterministic A/B control proven by existing 34/34 test suite
