feature request: type inference on Response type codegen

[devtempmac]

hello!

I just tried out encore hello-world (restapi) + encore's client code gen (typescript)

when I removed response type from the source, the codegen gives me 'void' response type:

export const get = api(
  { expose: true, method: "GET", path: "/hello/:name" },
  async ({ name }: { name: string }) => { //  removed: Promise<Response>
    const msg = `Hello ${name}!`;
    return { message: msg };
  }
);

import * as generatedClientSrc from './generated_client2';

const apiclient = new generatedClientSrc.default('')
const r = apiclient.hello.get("aa"); // type is: Promise<void>  but expected: Promise<{ message: string }>

is type inference on the roadmap? (or is it currently impossible?)

also, is there any way to express "branded-types", like zod's z.number.branded('user_id') ?
