Links can now be edited manually (title, summary, category, manufacturer, tags) via an inline edit form, with a "KI neu beschreiben lassen" action that re-fetches the URL and lets the AI regenerate all fields. Editing recomputes the search embedding. Also adds an app footer showing author, version, and hostname. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
