Session title bar does not update when changing working directory mid-session

Description

When a user instructs Claude to change to a different working directory during an active session, the working directory path displayed in the session title bar does not update to reflect the new location.

Steps to Reproduce

1. Start a new Claude Code session in directory A (e.g., /mnt/docker/genai-playground-dev)
2. During the session, instruct Claude to change working directory to directory B (e.g., ~/projects/hapimatic)
3. Claude successfully changes to the new directory and operates from there
4. Observe the session title bar still shows the original directory A

Expected Behavior

The session title bar should update to display the current working directory when Claude changes directories mid-session.

Actual Behavior

The title bar continues to show the original directory from session start, even though Claude is now operating from a different location.

Impact

• User confusion about which directory Claude is actually working in
• Potential for mistakes when managing multiple projects
• Inconsistency between displayed state and actual state

Environment

• Claude Code CLI
• Linux (Raspberry Pi OS)
