Documented attempt to execute pdftract CLI with OCR on degraded-200dpi.pdf.
Found that OCR feature requires leptonica system dependencies not currently
available in NixOS environment. CLI invocation and fixture file are valid,
but compilation fails due to missing lept.pc.
Acceptance criteria:
- Command executes: PARTIAL (valid syntax, build fails due to dependencies)
- Process starts: FAIL (blocked by missing leptonica headers)
- OCR process begins: FAIL (build prevents execution)
This is an environmental limitation, not a code defect.

Added verification note documenting attempts to run pdftract CLI on degraded
200 DPI fixture file. Found that current binary lacks OCR support, requires
rebuild with --features ocr and system dependencies (leptonica, libclang).
Closes bf-3n62c.
