login Session bug

### Preflight Checklist

- [x] I have searched [existing issues](https://github.com/anthropics/claude-code/issues?q=is%3Aissue%20state%3Aopen%20label%3Abug) and this hasn't been reported yet
- [x] This is a single bug report (please file separate reports for different bugs)
- [x] I am using the latest version of Claude Code

### What's Wrong?

Also hitting this on Ubuntu (Claude desktop app), same error:

{"type":"error","error":{"type":"permission_error","message":"Session is not fresh
enough to grant elevated access. Sign in again to continue.","details":
{"error_code":"session_stale_relogin"}},"request_id":"req_011CeuwL63H4edrzQjo9EzvB"}

Happened again after re-authenticating twice, so re-login isn't a lasting fix on my
end either. Would appreciate a silent token refresh or at minimum a heads-up
notification before force-logout, as requested above.

Claude desktop app version: [check Settings → About, or Help menu]
OS: Ubuntu [run `lsb_release -a` for exact version]

### What Should Happen?

Happened again after re-authenticating twice, so re-login isn't a lasting fix on my
end either. Would appreciate a silent token refresh or at minimum a heads-up
notification before force-logout, as requested above.

### Error Messages/Logs

```shell

### Additional Information

_No response_

No source file or test is identified in the report. Start by reproducing the failure with Claude Code 2.1.111 on Ubuntu/Debian under WSL, recording the exact version with `lsb_release -a` and the `session_stale_relogin` response. Done means the recurring authentication failure is resolved or users receive the requested warning before forced reauthentication.
