### Repro Steps

1. Open explorer
2. Navigate to any folder in linux disk. For example, /var
3. Shift + right click in folder
4. Select "open linux shell here" in context menu

Alternatively:
1. Open the folder as project in ide
2. Open terminal for project from ide

### Expected Behavior

Newly opened terminal starts in selected folder ( /var )

### Actual Behavior

Newly opened terminal always starts in linux user home folder ( ~ )

### Diagnostic Logs

_No response_

Start by reproducing the issue through Windows Explorer's "open linux shell here" action and an IDE project terminal, using /var as the selected folder. Trace the WSL launch path responsible for setting the initial working directory; done means the new terminal starts in the selected Linux folder rather than the user's home directory.
