Subject: [PATCH] Implement GraphQL Introspection Field and Type System

This PR implements the IntrospectionField struct and makes several improvements to the GraphQL introspection type system:

1. Implemented IntrospectionField with all required properties
2. Created TypeRef for consistent type references
3. Updated all collection fields to use slices where appropriate
4. Implemented IntrospectionEnumValue
5. Fixed InputFields in IntrospectionInputObjectType

These changes create a more accurate representation of the GraphQL type system for introspection.

Closes # 1
