Add Api Endpoint

Create a new Minimal API endpoint in src/Feirb.Api/.

Instructions

Given an endpoint description (from args or ask the user), create the following:

1. DTOs in src/Feirb.Shared/

• Create request/response record types in the appropriate file or a new one
• Use record types with primary constructors
• Place in Feirb.Shared.Models namespace

2. Endpoint Group in src/Feirb.Api/Endpoints/

Create or extend a static class following this pattern:

namespace Feirb.Api.Endpoints;

public static class {Feature}Endpoints
{
    public static void Map{Feature}Endpoints(this WebApplication app)
    {
        var group = app.MapGroup("/api/{feature}")
            .WithTags("{Feature}");

        group.MapGet("/", GetAllAsync);
        // ... more endpoints
    }

    private static async Task<Results<Ok<ResponseDto>, NotFound>> GetAllAsync(
        IService service,
        CancellationToken cancellationToken)
    {
        // Implementation
    }
}
