Proposed solution

I can not get the point why this does not support WSL terminal setup provided a MS product.
Please support it. And vim style will be better.

Works for me on WSL just fine. Perhaps be more specific with your errors.

I mean the command to setup-terminal and the error I got when to run it:

   If you're running WSL from VS Code, Windsurf or Cursor, please switch to a supported terminal within the IDE (e.g. PowerShell or Command Prompt) and run
   `/terminal-setup` again.`

I ran it from WSL and the shell is fishell.
did I miss anything?
