7049966def
When the error body already advertises OAuth endpoints, `/mcp add` and `/mcp reauth` use `authResult.oauth` directly and skip `discoverOAuthEndpoints`, so scopes advertised only in the RFC 9728 protected-resource metadata document never reach the grant. Add exported `fetchResourceMetadataScopes(url, opts?)` that fetches the metadata doc and returns `scopes_supported` / `scopes` / `scope`. Hoist the shared `readMetadataScopes` reader out of `discoverOAuthEndpoints`. At all three call sites (wizard, `/mcp add`, `/mcp reauth`), when `oauth` is populated from the JSON body but `oauth.scopes` is empty and `authResult.resourceMetadataUrl` was advertised, fetch the metadata and merge scopes onto `oauth`. Regression tests cover the resource-metadata fetch and its failure/empty-doc paths. Refs #4467
