2.42.0

(feat): Add support for semantic distinction between nullable<T> and optional<T> types via use-nullable-annotation flag. When enabled, nullable<T> generates as raw type T with @Nullable annotation, while optional<T> remains as Optional<T>. This provides proper API semantics for fields that can be null vs those that may be absent from requests.
