jedarden f805e52fa3 Add four research documents focused on readable text production 
- type3-font-extraction: CharProcs stream parsing, TeX/dvips naming
  conventions, dHash shape fingerprinting, nested font stacks, OCR fallback
- watermark-and-background-separation: five PDF watermark mechanisms,
  transparency tracking, cross-page repetition, WCAG contrast detection,
  raster inpainting, diagonal watermark removal pipeline
- historical-and-degraded-document-extraction: eight degradation categories,
  bleed-through removal, illumination correction, Sauvola binarization,
  stroke reconstruction, Fraktur/long-s handling, confidence-gated output
- complex-layout-reading-order: baseline clustering, XY-cut, Docstrum,
  RLSA smearing, mixed-layout detection, sidebar/inset/footnote ordering,
  perplexity-based confidence with natural_order fallback
