v1.0.0

Added

• First release of documentation-actions: CI/release foundation, composite
  actions (star-request, auto-rebase, markdownlint, lychee-link-check,
  docusaurus-build, awesome-list-checks), reusable workflows (test-deploy,
  pages-deploy, changelog, docs-index, catalog-api, auto-rebase, star-request,
  markdownlint, link-check), examples, and the floating v1 major tag for
  consumers.

Fixed

• Release PRs on rel/vX.Y.Z no longer fail CI: changelog validation skips them and the changelog unit test uses a fixture instead of a real entry.
