description	Create a new final readonly DTO class with Valinor-compatible constructor
disable-model-invocation	true

Create a new DTO class following project conventions:

• final readonly class with constructor promotion
• Place in src/v1/Dto/ or src/v3/Dto/ based on API version
• All properties as constructor-promoted readonly parameters
• Use appropriate PHP types (string, int, ?string for nullable)
• Apply relevant traits (HasSource, HasLanguage, etc.) if applicable
• Namespace: Ivuorinen\BusinessDataFetcher\{v1|v3}\Dto
• Generate a corresponding Pest test in tests/Unit/
• Read existing DTOs first to match style
