Signature

protected _substitutionsVariables: XpmLiquidSubstitutionsVariables;

This extended variable hierarchy combines the base collection variables with configuration-specific context, enabling accurate template evaluation.

Extension hierarchy:

Starts with parent collection's base variables (env, os, path, package).
Extended with properties: Merged from inheritance chain and local properties.
Extended with matrix: Parameter values for template-generated configurations.
Extended with configuration: The configuration object itself (name, dependencies, properties) accessible for self-reference.

This complete context is used for all substitutions within the configuration: properties, dependencies, devDependencies, and actions.
