Early access: Declarative Custom Data Definitions

Declarative custom data definitions offer a streamlined approach for managing and maintaining metafields and metaobjects. Key benefits include:

• Metafield and metaobject definitions are organized in TOML, and managed through the improved app dev command.
• Shopify automatically distributes these definitions to multiple shops simultaneously, significantly speeding up migration processes.
• Updates are atomic, ensuring that all stores consistently maintain the same version of your definitions.
• All declarative definitions include app-scoped limits, which prevent resource competition among different apps.
