Fügt die Kapiteldateien in Lesereihenfolge (manifest.json) zu einer Markdown-Datei mit dem Original-EPUB-Namen (.md) zusammen. Dabei werden: - Links zwischen Kapiteln zu Sprunglinks in der Gesamtdatei, - kollidierende Anker pro Kapitel umbenannt, - Medienpfade relativ zum Ziel umgeschrieben, - doppelte Fußnotendefinitionen entfernt, - Code nie verändert. Optionen -o, --toc, --no-frontmatter und --force; abschließender Linkcheck. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
