daniel 41cbbea00c perf(dashboard): reducir payload del home 87% y restaurar caching en Cloudflare
- Split components.json: índice sin content (1.9 MB / 249 KB br vs 15.6 MB / 4.15 MB br).
  Generador produce component-content/{type}/{slug}.json por componente y auto-copia
  a dashboard/public/. Página de detalle carga contenido on-demand via fetchComponentContent().
- Restaurar cabeceras de caché y seguridad perdidas en la migración Vercel→Cloudflare:
  _headers con Cache-Control max-age=86400 para JSONs, immutable para _astro/*,
  y HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy en todas las rutas.
- Eliminar dashboard/vercel.json (config muerta desde migración a Cloudflare Pages).
- Diferir hidratación: ClerkIsland y AuthButton client:load → client:idle;
  SaveToCollectionButton → client:visible.
- Eliminar gpt-tokenizer del bundle del navegador: reemplazado por estimación chars/4.
- Actualizar .claude/rules/dashboard.md para reflejar hosting en Cloudflare Pages.
