website-speed-fix

Audit a URL with Google PageSpeed Insights and apply concrete speed fixes to the current working directory. Detects stack (Next.js, Vite, Astro, SvelteKit, Nuxt, WordPress, plain HTML), maps PSI audits to remediation steps via audits.md, applies stack-specific recipes from playbooks.md, and verifies with a post-apply re-audit. Plan-then-apply by default: never edits without user approval unless `--apply` is passed.
