fix: propagate __slots__ to generic parameterizations (#13215)

fix: sort union args to put subclasses first for correct serialization When a union contains both a parent class and its subclass (e.g. Parent | Child), pydantic-core's union serializer uses the first matching schema. Since isinstance(child_instance, Parent) is True, the Parent schema was incorrectly selected first, causing the child's extra fields to be dropped during serialization. The bug was most visible when the parent model had a field with a default whose type was not an exact match for the field annotation (e.g. a=float=0 where the default is an int). In that case pydantic-core would match the Parent schema for a Child instance and serialize only the Parent fields. Fix: add a stable sort in _union_schema so that subclasses come before their parent classes. Only types that are strict subclasses of other union members are moved; unrelated types preserve their original relative order. Fixes #12099
