What's Wrong?

With the Claude Code for VS Code extension installed (v2.1.32), opening a Claude terminal window and issuing the /ide command gives the following output:

Select IDE
 Connect to an IDE for integrated development features.

 No available IDEs detected. Make sure your IDE has the Claude Code extension or plugin installed and is running.

 Enter to confirm · Esc to cancel

In the output for the Claude VSCode plugin, I can see:
