Zero-runtime-dependency document-parsing gem: parses PDFs, DOCX, XLSX, and images (with OCR), statically linking MuPDF and Tesseract directly into the compiled gem at install time, so no system libraries or external tools need to be separately installed. This trades a heavier, slower install (native compilation of two large C libraries) for zero runtime dependency headaches afterward — no version mismatches with a system-installed MuPDF or Tesseract to worry about.
