Convert source documents (PDF / Word / Excel / PowerPoint / EPUB / HTML / Jupyter / subtitles / web URL) into clean Markdown with images extracted alongside. Default is a sensible auto-clean transcription; use --raw for archival fidelity, or combine --filter-images / --no-images for image control. Also batch-converts directories. Use when the user asks to turn a document into Markdown, "extract text from a PDF", "把文档转成 md", "网页转 markdown", "批量转 md".
