v0.11.0

Added

• Stdlib @dataclass maps onto real object/input types. A dataclass
  response (or a dataclass field nested inside a model, and vice versa)
  becomes a GraphQLObjectType / GraphQLInputObjectType like a
  BaseModel or TypedDict: annotations from get_type_hints, output
  nullability from the annotation (defaults always materialize), input
  requiredness and literal defaults from the field definitions
  (default_factory fields are optional without a GraphQL default —
  FastAPI materializes them, a 422 surfaces as a field error).
  ClassVar/InitVar never become fields. FastAPI treats dataclasses as
  first-class citizens on both sides, so validation and serialization ride
  the native stack — the runtime path needed no changes. Recursive
  dataclasses get the true-depth contract like any recursive type.
