// Step 9 test — the thin-catalog state (against a workspace copy):
//   - no plugins/, no shared/, no scripts/sync-design-system.mjs (SC4)
//   - CONVENTIONS.md exists + carries the Forgejo / conventional-commits / three-doc rules (D6)
//   - marketplace.json + README.md + GOVERNANCE.md remain
//   - the rewritten README has zero local plugins//shared/ links and uses external Forgejo repos
//   - the stale playground-design-system version is corrected from plugin-map (v0.6.0)
// Pattern: plugins/config-audit/tests/*.test.mjs.
