PDF text extraction, dependency-free.

This reads the text layer; it does not render and it does not OCR. The strategy is deliberately structural rather than xref-driven: real files from these catalogs have broken, hybrid, or stream-based cross-reference tables, so objects are collected by scanning for N G obj … endobj and then expanding every /ObjStm compressed object stream. Two of three sample files from arXiv, BIS, and the Internet Archive carry 30+ object streams, so skipping them would lose most of the document.

Character mapping comes from each font's /ToUnicode CMap when present. Without one, a simple font's bytes are read as WinAnsi and a composite font is reported as lossy rather than silently emitting the wrong glyphs.
