Environment

Steps to Reproduce

1. Have a previous Claude Code session
2. Run claude --continue
3. Error occurs

Expected Behavior

Actual Behavior

Notes

The error appears to be in the session/conversation loading code where a value expected to be a string is undefined before .trim() is called on it.
