Error: resolveCoworkPaths builds VHDX path using %LOCALAPPDATA%\Claude\vm_bundles\... but the bundle lives in %APPDATA%\Claude\vm_bundles\...

Claude needs to amend the code in the recent update.
Fix in code: resolveCoworkPaths should use app.getPath('userData') (Roaming) consistently with what the VM subprocess uses
