/// Macro to register trait object conversions for custom traits.
///
/// This macro automatically generates serializers for `Box<dyn Trait>` trait objects.
/// Due to Rust's orphan rules, only `Box<dyn Trait>` is supported for user-defined traits.
/// For `Rc<dyn Trait>` and `Arc<dyn Trait>`, wrapper types are generated (e.g., `TraitRc`, `TraitArc`),
/// either you use the wrapper types or use the `Rc<dyn Any>` or `Arc<dyn Any>` instead if it's not
/// inside struct fields. For struct fields, you can use the `Rc<dyn Trait>`, `Arc<dyn Trait>` directly,
/// fory will generate converters for `Rc<dyn Trait>` and `Arc<dyn Trait>` to convert to wrapper for
///
/// The macro generates:
/// - `Serializer` implementation for `Box<dyn Trait>`
/// - `Default` implementation for `Box<dyn Trait>` (uses first registered type)
///
/// **Note**: Your trait must extend the `Serializer` trait.
/// The `as_any()` method is automatically provided by the `Serializer` trait.
