- Relocate seed.sql to scripts/ so wrangler d1 migrations apply
doesn't treat it as a migration; update package.json, setup.mjs,
README, and all AGENTS.md references.
- Add src/lib/schema-org.ts builders (LocalBusiness, FAQPage,
BlogPosting, BreadcrumbList) and emit JSON-LD via Base.astro.
- Add lastmod to sitemap entries.
- Set real site domain, worker route, and D1/KV ids.
- Improve image loading hints and heading semantics across site
components; switch BlogIndex to client:idle.
