Research direction

Start with the Microsoft string-str documentation and YARA PE module reference linked in the issue, then locate Goblin's PE parsing entry point for version-resource strings. Determine how OriginalFilename should be represented and expose it consistently; done means the field is parsed and available to callers with coverage for the new behavior.
