Atmos JSON Schema System

Overview

Atmos uses JSON Schema (Draft 2020-12) to validate configuration files, provide IDE auto-completion, and catch configuration errors early. Two schemas cover the core file types:

1. Stack manifest schema -- Validates stack YAML manifests (stacks/**). Published at https://atmos.tools/schemas/atmos/atmos-manifest/1.0/atmos-manifest.json and registered with SchemaStore as https://json.schemastore.org/atmos-manifest.json. Used by atmos validate stacks and by IDEs for auto-completion.

2. CLI configuration schema -- Validates atmos.yaml itself (every configuration section the CLI reads). Published at https://atmos.tools/schemas/atmos/atmos-config/1.0/atmos-config.json. Used by atmos validate schema config and by IDEs for auto-completion. This schema is generated from the Atmos configuration code, so it always matches the options the installed release actually supports -- including YAML function alternatives (like logs: !include shared.yaml) and descriptions for hover text.
