Nit: "on startup" is somewhat ambiguous. It sounds synonymous to "on boot" to me
but this is not actually what happens. The auto-launch code is triggered
whenever we reach the login screen, whether on boot, on logout or on crash.

Done.

   virtual void StartAppLaunch(const std::string& app_id,
-                              bool diagnostic_mode) = 0;
+                              bool diagnostic_mode,
+                              bool is_auto_launch) = 0;
 
   // Starts the demo app launch.
   virtual void StartDemoAppLaunch() = 0;
