Atmos Devcontainer

Purpose

Atmos provides native devcontainer management for creating standardized, reproducible development environments. It provides built-in orchestration that integrates with Atmos authentication, toolchains, and project configuration, replacing the need for external orchestration tooling like Geodesic (though Geodesic container images remain fully supported).

Note: The devcontainer feature is currently experimental. By default (settings.experimental: warn), Atmos displays a warning but runs the command. Set settings.experimental: silence in atmos.yaml to suppress the warning, or disable to block experimental commands entirely.
