Final German naming cleanup in dev-process:
- vorlagen/ -> templates/
- vorlagen-word/ -> templates-word/
- tools/generate_word_vorlagen.sh -> tools/generate_word_templates.sh
- *-vorlage.md / *-vorlage.docx -> *-template.md / *-template.docx
- Review-Protokoll-vorlage.* -> Review-Minutes-template.*
- angebot-vorlage.* -> quote-template.*
- angebot-beispiel.html -> quote-example.html
All references in README.md, toolstack/toolstack.md, build_word_template.py,
and generate_word_templates.sh updated. The master Word style template
(slohmaier-doc-template.docx) was already English-named.
The dev-process repo is now fully English in both content and structure.
