Macro expansion possibly breaking the compiler when service class has non-empty constructor

[keynmol]

I've not really dug deep into it, but here's a repro:

//> using dep "tech.neander::smithy4s-deriving::0.0.2"
//> using dep com.disneystreaming.smithy4s::smithy4s-http4s::0.18.22
//> using option -experimental

import smithy4s.*, deriving.{given, *}, aliases.*

import scala.annotation.experimental // the derivation of API uses experimental metaprogramming features, at this time.
import cats.effect.IO
import smithy4s.http4s.SimpleRestJsonBuilder


@experimental
@simpleRestJson
class IOService(a: Int) derives API:
  @readonly
  @httpGet("/httpbin/ip")
  def hello(): IO[String] = IO.pure("127.0.0.1")


def routesResource(service: IOService) =
  SimpleRestJsonBuilder
    .routes(service.liftService[IO])
    .resource
    .map(_.orNotFound)

This produces an error:

Compiling project (Scala 3.4.2, JVM (17))
[error] ./test.scala:26:6112
[error] wrong number of arguments at constructors for (a: Int): IOService: (proxy.super.<init> : (a: Int): IOService), expected: 1, found: 0

The error goes away if you remove the a: Int parameter in IOService constructor
