The AddAssetReferenceRequest struct is missing a Validate() method. Following the pattern established by similar request structs like FileAddRequest and DirectoryAddRequest, this should include validation to ensure required fields (StorageID and Name) are provided.

Suggested change

	// Validate checks if the AddAssetReferenceRequest is valid.
	// It implements the crowdin.RequestValidator interface.
	func (r *AddAssetReferenceRequest) Validate() error {
	if r == nil {
	return ErrNilRequest
	}
	if r.StorageID == 0 {
	return errors.New("missing required field: StorageID")
	}
	if r.Name == "" {
	return errors.New("missing required field: Name")
	}
	return nil
	}
