- Convert 26 AsciiDoc files to Markdown across getting-started/, tools/, operations/, reference/, standards/
- Create index.md homepage and contributing.md
- Add deploy-docs.yml workflow (Python 3.12, mkdocs-drawio)
- Move draw.io diagrams to docs/assets/diagrams/
- Archive all .adoc files to docs/_archived_adoc/
- Add .vale.ini and styles/Microsoft/ (44 rules) for Vale linting
- Fix broken anchor links in badge-standards.md
