[BUG] Claude leaves behind locked panels in VSCode

What's Wrong?

Opening new tabs using the VSCode/Cursor extension creates new locked tab groups when you have other files already open. This is slightly annoying behaviour when I want to manage multiple Claude Code tabs + files.

What Should Happen?

Other extensions explicitly expose an 'Auto Lock Groups' setting to control this:

It would be great if the Claude Code extension could do the same.

This issue was previously raised here: #7752
However, that issue was incorrectly labelled as a duplicate of #6917 and is now locked.

Steps to Reproduce

1. Open VSCode.
2. Open a file.
3. Open Command Palette (Cmd+Shift+P on Mac)
4. Select 'Claude Code: Open in New Tab'
5. A new Claude Code tab is created as a locked side group.
