Role constructor

Declares the design role of a class or method within a Jetleaf application.

This annotation is intended for design-time metadata and architectural documentation. It can also be used by tooling (e.g., code generators, analyzers) to enforce architectural rules.

Example

@Role(DesignRole.APPLICATION)
class UserService {
  Future<User> findById(String id) {
    // business logic here
  }
}

@Role(DesignRole.APPLICATION)
class UserController {
  final UserService service;

  UserController(this.service);

  @Get('/users/:id')
  Future<User> getUser(String id) => service.findById(id);
}

Note: @Role is not required for Jetleaf runtime behavior, but it is highly recommended for clarity and tooling support.
