[idea] jwt token handling internal browser

[Nsomnia]

since qt web engine doesn't work for anyone and Suno doesn't allow custom hooks I'm the url then:

To enable Google OAuth in a C++ desktop app (bypassing Qt WebEngine issues), use a lightweight, embeddable webview library that allows setting a custom mobile User-Agent, simulating an Android browser. Microsoft/webview2 (Windows) or zserge/webview (cross-platform) are recommended, configured to emulate mobile device headers.

Key Implementation Steps
Set Mobile User-Agent: Configure the webview to send a mobile UA string (e.g., Mozilla/5.0 (Linux; Android 10; K) AppleWebKit/537.36...).
Handle OAuth Redirects: Use a "Loopback IP" (127.0.0.1) for the OAuth callback URL, which is the secure, recommended method for native apps.
Intercept Auth Code: Monitor the webview navigation for the callback URL, extract the code parameter, and exchange it for tokens via your C++ backend.

Recommended Libraries
WebView2 (C++/WinRT): Best for Windows desktop, supports modern web standards.
zserge/webview: Lightweight C/C++ cross-platform wrapper (uses Edge/Webkit/WebKitGTK based on OS).
Google Security Requirement
Do not use embedded webviews for the entire login flow if possible, as Google restricts this due to security risks (man-in-the-middle). The preferred method is using system browsers or Android Custom Tabs to handle authentication.

Futher exploiration of the suno endpoints at s.prod.suno.com (or similar) and studio-api.prod.suno.com shows that we should be able to do google oauth redirects back to localhost among other means of handling this, plus programmatically with the new suno frontend feature being nearly ther at a base levl.
