feat(seo): add GEO meta tags and JSON-LD for generative engines
Add explicit crawler policy for GPTBot/ClaudeBot/PerplexityBot/Google-Extended and others, citation-friendly abstract/summary meta, plus HowTo, BreadcrumbList, TechArticle and Person JSON-LD blocks so generative search engines can index and cite sql2er accurately.
