Command (run from scripts/partner_link_health):
  ./partner_link_health_wrapper_with_json_summary.sh scripts/partner_link_health/partners.json scripts/partner_link_health/wrapper_out
Notes:
  - Wrapper cd's to repo root, so config must be passed as a repo-root-resolvable path.
  - This run is qualitative-only (PASS/FAIL, presence of backlink needles), no scoring.
