Identify and document the correct CLI flags for running pdftract in text
extraction/OCR mode. Verification: notes/bf-2gfd1.md.
Key findings:
- --text <PATH>: Output plain text to PATH (use '-' for stdout)
- --ocr: Enable OCR for scanned pages (requires 'ocr' feature)
- --ocr-language <OCR_LANGUAGE>: OCR language codes (comma-separated)
All acceptance criteria PASS (correct CLI subcommand identified, CLI help
confirms flags exist, flag syntax documented). Closes bf-2gfd1.
