chore(humanizer): README test-count badge + self-audit terminal humanization

- Bump README test-count badge: 635 → 792 (matches filesystem after Wave 0–5)
- Wire formatSelfAudit() through humanizeEnvelope + humanizeFindings so the
  terminal-output path renders humanized finding titles. The --json path is
  unchanged — only the prose terminal render is humanized.
- readmeCheck.passed now returns true; configGrade A (97), pluginGrade A (100)
