Tech stack & purpose

This is a Microsoft-maintained repository containing pre-built development container images published to the Microsoft Container Registry. The repository provides infrastructure for building and managing devcontainer images across multiple architectures and variants, with a Node.js-based build CLI (`build/vsdc`) that handles image compilation, registry pushes, and dependency tracking. The system supports multiple Linux distributions (Debian, Alpine, and Red Hat), multiple processor architectures (x86_64 and ARM64), and publishes both stable release-tagged images and weekly "dev" preview builds from the main branch via automated GitHub Actions workflows. Image configuration is managed through `manifest.json` files that define build parameters, tagging strategies, variants, and dependencies, with support for tracking third-party open-source packages and generating component manifests and version history documentation.
