What's Wrong?

preferredName is set in ~/.claude/settings.json but the greeting banner does not display it on macOS. The same version on a remote Linux server shows the name correctly.

What Should Happen?

preferredName set in ~/.claude/settings.json should be displayed in the greeting banner.

Welcome back 홍길동!
shown in the greeting banner.
