KRB meta descriptions only bundle

Source: WP DB _genesis_description/_yoast_wpseo_metadesc matched to Sylvain sitemap-map.json
Source pages: 85
Descriptions available: 49
Pages with no source description: 36

Run order:
1. Run krb-meta-descriptions-only-20260612-134013-preflight.js first. It is read-only.
2. If matches look right, run krb-meta-descriptions-only-20260612-134013-live.js.

The live script only calls page.setDescription() on matched pages. It does not create pages, update titles, insert components/body content, or publish.
See krb-meta-descriptions-only-20260612-134013-manifest.json for the exact source mapping and missing-description list.
