Make PPTX run-count comparison configurable for task b8adbc24 (#443) Add an `examine_run_count` flag to `compare_pptx_files` (defaulting to true) and gate run-count mismatch checks for both text paragraphs and table cells. Disable this check in `b8adbc24-cef2-4b15-99d5-ecbe7ff445eb.json` to prevent false negatives from non-semantic LibreOffice run segmentation differences.
