Enable auto-updates

By default, third-party marketplace plugins do not auto-update. To enable automatic updates, either:

1. Via the UI: Run /plugin → select the Marketplaces tab → choose the marketplace → Enable auto-update

2. Via settings: Add to your .claude/settings.json:

   {
     "extraKnownMarketplaces": {
       "prelude-claude-plugin": {
         "source": {
           "source": "github",
           "repo": "preludeorg/prelude-claude-plugin"
         },
         "autoUpdate": true
       }
     }
   }
