[BUG] Title: Auth URL line-wraps in JetBrains IDE terminal, making clickable link invalid

What's Wrong?

During the authorization flow (claude first run), the authentication URL is printed to the terminal without any line-wrap protection. In the JetBrains IDE embedded terminal (IntelliJ IDEA on Windows), the URL gets split across two lines, and clicking it opens only the first fragment — resulting in an invalid URL and a failed auth attempt.

Actual behavior: Only the first line of the split URL is followed. The browser opens an invalid/incomplete URL.

Workaround: Manually copy the full URL (both line fragments) and paste it into the browser address bar.

Environment:

Claude Code version: 2.1.158
OS: Windows 11
Terminal: JetBrains IntelliJ IDEA embedded terminal (via JetBrains Toolbox)

What Should Happen?

The full URL opens in the browser and authentication succeeds.

Error Messages/Logs

Steps to Reproduce

1. Open the embedded terminal inside IntelliJ IDEA (Windows)
2. Run claude for the first time to trigger the auth flow
3. Observe the authentication URL printed to the terminal
4. Click the link
