Class PolymorphicConverter

Newtonsoft converter that resolves a discriminated union by reading its discriminator property (at any position in the object) and mapping the value to the concrete type registered via JsonSubTypeAttribute / JsonSubTypeNameAttribute. On write it emits the discriminator for the runtime type. It is attached to a hierarchy's root by the generator and inherited by every subtype.

Recursion is broken with the canonical per-thread CanRead / CanWrite toggle: after resolving the concrete type, the converter suppresses itself for exactly the one nested (de)serialization of that type, so its own members are handled by the default contract while any polymorphic fields WITHIN it (including recursive references back to the same union) are still routed through the converter.
