/**
 * Structural type definitions for the Langium service layer.
 *
 * The LangiumServices type is a fairly volatile part of langium's API,
 * changing shape across releases. These structure props try to isolate to
 * only the parts we're interested in, so langium-ai-tools can work with any
 * langium 4.x release
 *
 * Stable langium types (AstNode, URI, CstUtils, etc.) are imported directly
 * from the langium peer dependency — only the service types are abstracted here.
