[BUG] OAuth login & `claude auth logout` crash with "null is not an object (evaluating 'T.history')" on macOS

What's Wrong?

Browser OAuth login completes successfully (the browser shows "You're all set"), and a credential is written to the macOS Keychain (service = "Claude Code-credentials"). But immediately after, the CLI runs a post-auth step (token finalize/refresh) that crashes with:

OAuth error: null is not an object (evaluating 'T.history')

The same crash occurs in claude auth logout, which exits non-zero and fails to remove the keychain credential.

What Should Happen?

After a successful browser OAuth, the CLI should finalize the session without crashing and show loggedIn: true.

Steps to Reproduce

When I run in terminal: claude login. The browser OAuth flow gets completed and says "You're all set." But the terminal prints:

OAuth error: null is not an object (evaluating 'T.history'
