Duplicate "Loaded cached credentials" message during CLI startup

Hi everyone 👋

I noticed that when using Google OAuth with the Gemini CLI, the message “Loaded cached credentials” appears twice during startup.

🔎 Root cause:
The authentication logic was being executed in both the launcher process and the final child process after relaunch, resulting in the duplicate message.

🛠 What I did:

Moved the initializeApp() call so that authentication only runs once, in the final stable child process.

This completely eliminates the duplicate message and simplifies the startup flow.

You can see the full details and test plan in my PR here:
