Remote functions: Build fails with shared variables from <script module>

[Blackwidow-sudo]

Describe the bug

As i've mentioned in #14682 (comment), when you share a validation schema (or something else) from a <script module> in routes/+page.svelte with your routes/login.remote.js the build will fail because the order of declarations is wrong in the output files of .svelte-kit/.

For example in my case the output looked like this:

import { z as attributes } from "./index.js";
import "@sveltejs/kit/internal/server";
import "./utils.js";
import "@sveltejs/kit";
import { f as form } from "./query.js";
import * as z from "zod";
import { init_remote_functions } from "@sveltejs/kit/internal";
const m = /* @__PURE__ */ Object.freeze(/* @__PURE__ */ Object.defineProperty({
  __proto__: null,
  get login() {
    return login;
  }
}, Symbol.toStringTag, { value: "Module" }));
const login = form(schema, (data) => {
  console.log(data);
});
init_remote_functions(m, "src/routes/form/login.remote.js", "dth4yy");
for (const [name, fn] of Object.entries(m)) {
  fn.__.id = "dth4yy/" + name;
  fn.__.name = name;
}
const schema = z.object({ email: z.email(), password: z.string().min(8) });
function _page($$renderer, $$props) {
  $$renderer.component(($$renderer2) => {
    $$renderer2.push(`<form${attributes({ ...login.preflight(schema) })}><label>Email: <input${attributes({ ...login.fields.email.as("email") }, void 0, void 0, void 0, 4)}/></label> <label>Password: <input${attributes({ ...login.fields.password.as("password") }, void 0, void 0, void 0, 4)}/></label> <button type="submit">Login</button></form>`);
  });
}
export {
  _page as _,
  m,
  schema as s
};

As you see, the schema is used in the remote form but declared later.

Reproduction

Just run npm run build in:
