refactor: rede_korrigieren.py → abschrift_korrigieren.py, Texte neutral
Das Programm verarbeitet beliebige gesprochene Beiträge (Reden, Vorträge, Interviews, Videos). Prompts und Texte sprechen von „Beitrag“ statt „Rede“; README-Titel passend zum Projektverzeichnis youtube_abschrift_korrigieren. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
