Gitlab Ci Validator

This validates GitLab CI/CD pipelines through syntax, best practices, and security checks before you push or merge. It catches the usual suspects: hardcoded secrets, missing cache configs, undefined job dependencies, and sketchy curl pipe bash patterns. The workflow is gated (syntax first, then security, optionally best practices in strict mode), which makes sense for CI integration. It wraps Python validators in shell scripts with automatic venv setup if PyYAML is missing, and there's an optional local execution test if you have gitlab-ci-local and Docker installed. Solid for catching configuration mistakes early, though it won't replace actually running your pipeline to see what breaks in practice.
