Gemini CLI fixes an infinite auth loop in its core OAuth flow

The google-gemini/gemini-cli PR fixes a bug that could trap users in an infinite authentication loop after sign-in.

The fix waits for asynchronous writes to oauthcreds.json so credential saves are serialized instead of overlapping and corrupting the file.
It also forces prompt: 'consent' when starting OAuth, ensuring users are explicitly re-authorized instead of falling into a silent re-auth failure state.
The validation steps are straightforward: delete the credentials file, authenticate once, restart the CLI, and confirm it loads credentials without asking again.
