SEO Audit

Runs a technical SEO audit of a live website and its codebase from the terminal and reports findings with evidence, ranked by how much each one keeps pages out of search results. Use when a user asks for an "SEO audit", "technical SEO check", "why did our traffic drop after the migration", "why isn't Google indexing these pages", "check robots.txt, sitemap and canonicals", or "check our Core Web Vitals". Covers crawlability, indexing signals, canonical URLs, sitemaps, JavaScript rendering, structured data presence and Core Web Vitals, with the command for each check and how to read its result.
