This PR adds VineJS validator generation functionality to the @adocasts.com/dto package. It allows users to generate validators based on model properties, similar to how DTOs are currently generated.

Features Added

• New ValidatorService class for mapping model properties to VineJS validator types
• New Ace commands:
  • make:validators - Generate a single validator from a model
  • generate:validators - Generate validators for all models
• Integration with existing DTO generation:
  • Added --validator flag to make:dto command
  • Added --validator flag to generate:dtos command
• Validator stub templates:
  • main.stub for model-based validators
  • plain.stub for validators without models
• Comprehensive test suite for validator generation
• Updated documentation with examples and usage instructions

Implementation Details

• Model property types are mapped to appropriate VineJS validator types
• Optional properties are properly handled with .optional() modifier
• Relationships are mapped to vine.object() or vine.array() as appropriate
• DateTime properties are converted to vine.string().datetime()
• Validators are stored in the app/validators directory

Testing

All functionality has been thoroughly tested with:

• Unit tests for the ValidatorService
• Command tests for make:validator and generate:validators
• Integration tests for DTO and validator generation together

Documentation

• Added validator generation documentation to README.md
• Added examples of using generated validators
• Documented the mapping between model properties and validator rules
• Created validator_architecture.md with detailed design information
