Pull request overview

This PR migrates the repository’s CI/docs automation to use centrally maintained Eclipse S-CORE reusable workflows, replacing the previous combined “test + docs” workflow with a PR checks workflow plus a separate docs publishing workflow.

Changes:

• Remove the legacy combined workflow (test_and_docs.yml).
• Extend on-pr.yml to run unit tests via a local reusable workflow and build docs via the central docs workflow, and add tag/release triggers.
• Add docs-publish.yml to publish documentation via a central workflow after successful “PR Checks” runs, and convert _test.yml to be workflow_call-only.
