What's Wrong?

All versions greater than 0.92 have broken support for browser based SSO flows where the CLI displays a URL. The behavior on 0.92 and earlier (which is correct) is as follows.

1. User types Claude
2. Claude opens and immediately outputs auth link for user to click and open in browser

The behavior on 0.94 and up is the following

1. User types Claude
2. The do you trust this workspace prompt comes up
3. In the background via debug logs Claude outputs the auth link but does NOT make it visible in the terminal to be clicked

Logs:

1. Auth times out after 20 seconds
2. User can finally see auth link after waiting 20 seconds

This is breaking the ability to upgrade to any new versions

What Should Happen?

1. User types Claude
2. Claude opens and immediately outputs auth link for user to click and open in browser
