Revert CliFx removal; fix macOS CI hang by setting WorkingDirectory on Exec

The macOS CI timeout was caused by `dotnet run` detecting the
`.csproj` file in the working directory and running the GUI project
instead of the `.csx` script. The GUI app would launch, try to
initialize Metal/Skia graphics (no display on CI), and hang until
the 10-minute job timeout.

Fix: Set `WorkingDirectory="$([System.IO.Path]::GetTempPath())"` on
the `<Exec>` element so `dotnet run` runs from a clean directory with
no project file, correctly treating the `.csx` as a file-based app.
