llvm-native-core 0.1.16

//! clang_ci_cd — CI/CD integration for Clang builds.
//!
//! Covers:
//! - GitHub Actions: parse workflow YAML, run compilation steps
//! - GitLab CI: parse .gitlab-ci.yml, run compilation jobs
//! - Jenkins: parse Jenkinsfile, run pipeline
//! - CircleCI: parse .circleci/config.yml
//! - Travis CI: parse .travis.yml
//! - Azure Pipelines: parse azure-pipelines.yml
//! - Drone CI: parse .drone.yml
//! - Buildkite: parse pipeline.yml
//! - TeamCity: parse kotlin DSL
//! - CI result reporting: test results, compilation warnings, performance metrics
//! - CI artifact generation: compiled binaries, test reports, coverage data
//! - CI badge generation: build status, coverage percentage
//!
//! Clean-room reconstruction from public CI documentation and APIs.
