Use it now
Plugin marketplaces can now authenticate using the app's existing inference credential.
allowedPluginMarketplaces entries can now set credentialKind: "inferenceCredential" for url-sourced marketplaces. This sends the same credential the app already uses for its inference gateway or bootstrap server, so a marketplace hosted on that same origin needs no separate credential setup.
