[BUG] `claude auth login` hangs after opening browser, while plain `claude` prompts for pasted auth code

What's Wrong?

Running claude auth login opened the browser auth URL but then hung in the terminal and never showed Paste code here if prompted.

What Should Happen?

Running plain claude instead opened a browser link and then correctly showed Paste code here if prompted, which allowed login to complete.

claude auth login should either:

• show Paste code here if prompted, or
• complete login automatically after browser approval
