Walkthrough

This PR extends the normalization system to track and propagate schema definition/extension nodes through the normalization pipeline. It updates NormalizationSuccess with an optional schemaNode field, modifies the normalization factory's addSchemaDefinitionNode method to return the created node, removes unused deprecation-related imports, and updates tests to verify deprecated directive handling.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Extra attention areas:
  • Verify schemaNode propagation through normalize and batchNormalize call chains
  • Confirm schema extension handling logic correctly determines SchemaDefinitionNode vs SchemaExtensionNode creation
  • Validate test assertions align with deprecated directive mapping expectations and schema output

Learning: The checkSubgraphSchema.ts file already correctly implements linked subgraph functionality, using byName(linkedSubgraph.name, linkedSubgraph.namespace) to fetch target subgraphs and properly handles parse(newSchemaSDL) for schema building. The implementation doesn't need fixes for byId usage or schema parsing as it's already correct.
