Implement per-word validation filter for assisted-OCR BrokenVector path. Changes: - Add SpanSource::OcrAssisted variant to hybrid.rs - Add Span::ocr_assisted() helper method - Implement validate_ocr_with_position_hints() in ocr.rs - 5pt distance threshold for position validation - 0.4 confidence cap for rejected words - Linear scan for nearest-neighbor lookup - Add unit tests for validation filter Closes: pdftract-3s2i Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
