[BUG] claude setup-token/CLAUDE_CODE_OAUTH_TOKEN is not enough to authenticate claude

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)

What's Wrong?

I ran claude setup-token, got the token and exported in CLAUDE_CODE_OAUTH_TOKEN.
Run claude in a fresh container (where claude was never run before) with the exported token. Claude walks me through the usual startup process, theme, choice of authentication (oauth, anthropic key). I was expecting it to just start and be ready for operation

What Should Happen?

When claude is started with an exported CLAUDE_CODE_OAUTH_TOKEN it should just start without asking for authorization.
