How EmDash uses Clef to moderate the plugin registry

• Every plugin listing in the official EmDash plugin registry is now screened by Cloudflare's Clef decision model before it can appear in the catalog.
• Clef reviews the listing metadata, outbound links, icon, and screenshots for phishing, impersonation, offensive content, scams, and attempts to manipulate the moderation system.
• The registry is built on AT Protocol, so plugin authors publish signed releases from their own accounts.
