GitHub Actions CI/CD Workflow Generator

## Overview This crystal inspects your project's configuration files — `package.json`, `pyproject.toml`, `go.mod`, and others — and produces a fully configured GitHub Actions YAML that covers the entire CI/CD pipeline from code quality checks through multi-environment deployment. ## Supported Stacks - **Node.js / TypeScript** — npm, pnpm, and Yarn, with ESLint and TypeScript type-checking steps - **Python** — pytest, ruff, and mypy, with configurable test matrix - **Go** — `go test`, golangci-lint, and race detector - **Docker** — multi-platform build and push to Docker Hub or GHCR - **Multi-environment deployment** — staging and production gates with manual approval steps
