Make selector manifest tests platform-independent

Replace hardcoded "/tmp" paths with Path.GetTempPath() and build input paths dynamically. Update assertions to check the output filename and normalized directory path (using Path.GetFullPath and TrimEnd on DirectorySeparatorChar) so the tests work across platforms (e.g., Windows vs Unix) and with generated .g.cs suffixes.
