Author, edit, debug, and review the OpenVINO GitHub Actions CI infrastructure — regular (non-agentic) workflows under .github/workflows, reusable job_*.yml workflows, custom composite actions under .github/actions, CI helper scripts under .github/scripts, Dockerfiles under .github/dockerfiles, and the Smart CI / labeler / components configuration. Use when a user wants to add or change a build/test job or step, create or modify a reusable workflow, write or fix a custom action, adjust runners/containers/caches, wire up Smart CI for a component, pin action versions, fix workflow permissions/security, or debug a failing CI workflow's YAML. Do NOT use for gh-aw agentic workflows (*.md with gh-aw frontmatter — use ov-agentic-workflows), for diagnosing a specific product/test failure's root cause in C++/Python code, or for non-CI GitHub configuration.
