ci

ci centralizes reusable GitHub Actions workflows for the ov-ext-labs OpenVINO sandbox.

This repository is intentionally small and policy-focused:

• reusable workflows for component CI and upstream sandbox execution;
• reusable module-driven sandbox checks for upstream openvino pull requests;
• shared cache management and warm-target definitions for upstream sandbox jobs;
• shared CI conventions for gfx-plugin, java-api, and genai-java-api;
• self-validation for workflow/action/config authoring lives in .github/workflows/ci-self-checks.yml;
• MANIFEST.lock records the current integration topology and pinned managed-repository revisions;
• upstream sandbox module definitions live in config/upstream_pr_profiles.json;
• no product logic.
