Launch the full desktop Trading Engine with your current website session.
When signed in on the website, the launch button requests a desktop session token and passes it to the installed desktop app through the algowealths:// protocol.
The desktop app can reuse the same website entitlement context by syncing against /api/auth/desktop_session.php after launch.
If the app does not open, register the desktop protocol on Windows using the packaged protocol file generated by the updated builder.
