The extract_markdown stub was calling extract_text instead of extract_text_fn, causing a compilation error. This fixes the function name to match the exported function from extract_text.rs. This completes the extract_text PyO3 entry point implementation, which was already present in extract_text.rs and lib.rs. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
