Wren 0.4.0 "Pacificus"

SEO throughout. Every article and page gains a Search description field (with an automatic excerpt fallback), and every public page now carries canonical URLs plus Open Graph and Twitter card tags so shared links unfurl properly. New: a live sitemap.xml built from your published content, a robots.txt route for pretty-URL sites, and settings for a site-wide search description and social share image. Themes need no changes — tags inject automatically, or place {{seo_head}} in your theme to control placement. Upgrading: replace index.php; the database updates itself.
