All API calls now run via callAsyncJavaScript inside a background WKWebView, using the same fetch path the page itself uses — credentials are included automatically.\n- Fixed WebKit suspending the background WKWebView: a WKWebView with no window is throttled/suspended by macOS, preventing JS execution. The background WebView is now anchored in a transparent 1×1 NSWindow, keeping it active.\n- Fixed login window auto-closing before sign-in completes — login window loads `/login` and only detects auth when back on claude.ai (not on OAuth provider redirects)\n- Added `/api/organizations` as a final fallback for org ID resolution\n- Fixed Settings incorrectly showing \"Signed in\" after a failed refresh"
