[BUG] Adding folder as project does not change working directory (CWD remains parent folder)

Description

When adding a folder as a project in Claude Code Desktop (macOS), the working directory (CWD) does not change to the added folder — it remains the parent directory.

Steps to Reproduce

1. Open Claude Code Desktop
2. Add a folder (e.g. ~/Documents/Honda CR-V) as a new project
3. The project tab shows the correct folder name
4. Ask Claude: "what folder are you in?"

Expected Behavior

CWD should be /Users/username/Documents/Honda CR-V

Actual Behavior

CWD is /Users/username (parent directory, not the added project folder)

Environment

• Platform: macOS
• App: Claude Code Desktop
• Model: claude-sonnet-4-6
