Use `typeof(T)` instead of `input.GetType()` to preserve polymorphic serialization. When T is a base type with `[JsonPolymorphic]`, this ensures the `$type` discriminator is included. Using `input.GetType()` would serialize as the concrete type, bypassing polymorphic attributes.

…erializer Added unit tests to verify polymorphic serialization behavior when using typeof(T) instead of input.GetType() in the ToStream method. Tests validate that the $type discriminator is correctly included when serializing derived types through a base type parameter, which is required for proper polymorphic deserialization.

Description
Use
