* feat(ats): extract PDF text with pypdf before Poppler

Lead the ATS text-layer check with pypdf (BSD, optional pip install). Fall back to pdftotext -layout -enc UTF-8. No cache directory, no installer, no AGPL pymupdf. Windows users without Poppler still get a mechanical parseability check; visual review remains the last resort.
