Set up an end-to-end documentation site so contributors and users have
a unified, searchable, and publishable entry point for project docs.
- Add mkdocs.yml: Chinese-first language, light/dark palette, tabbed
navigation, indexed sections, glightbox for diagrams, and
pymdownx.snippets so community pages can pull from root governance
files (CONTRIBUTING.md, CODE_OF_CONDUCT.md, SECURITY.md) without
duplicating content.
- Add requirements-docs.txt pinning mkdocs-material and
mkdocs-glightbox.
- Build the docs/ skeleton: index, quickstart, guide, architecture,
development, modules, community. Migrate the seven generic manuals
from dc3/doc/ (QUICKSTART, ENVIRONMENT, LOGGING, TROUBLESHOOTING,
MODULES, DRIVER-AUTHORING, TESTING) and rewire their cross-doc
links. CHANGE.md, TITLE.md, and USAGE.md stay in dc3/doc/ because
docker-ci.yml depends on them; the docs site references them via
mkdocs snippets to keep a single source of truth.
- Add .github/workflows/docs.yml that builds with --strict on push to
release and deploys via actions/deploy-pages.
- Rewrite dc3/doc/README.md as a migration pointer to the new site
and to the three retained release-flow files.
Verification: mkdocs build --strict passes locally; snippets render
correctly; GitHub Pages already enabled in workflow mode via gh api.
