* docs: add new pages to GitHub Pages navigation menu

- Add Agile/Scrum Workflows to Guides section
- Add Reference Documentation index to Reference section
- Fix reference links to use correct permalinks (/reference/architecture/, etc.)

The sidebar navigation menu is hardcoded in the layout file, so these
pages need to be manually added to appear in the left sidebar.

- Code background: #1d2d50 (darker blue)

Mermaid diagrams now use dark theme with cyan accents for better
readability and visual consistency with specfact.io documentation site.
