Normalize path separators before sorting for cross-platform consistency

Sort by forward-slash-normalized relative paths instead of raw OS paths,
so file IDs are assigned identically on Windows and Linux. The remaining
cross-platform hash difference is due to .NET runtime ZLib implementation
differences (not fixable at application level).
