What
/upgrade opens the page for switching to a higher plan in your web browser. When it cannot open a browser, it now prints "Couldn't open your browser. Open this page to upgrade:" followed by the page's address.
Why
This helps when Claude Code runs where no browser can open, such as on a remote machine you reach over SSH (a remote terminal connection).
