Fastify preHandler helper for loading a document by id from route params.

import { createGetByIdPreHandler } from "@typed-mongo/fastify";

fastify.get("/users/:id", {
  preHandler: createGetByIdPreHandler({
    param: "id",
    repository: UserRepository,
    attachTo: "user",
  }),
});

The preHandler attaches the document to request[attachTo]. Missing documents throw TypedMongoNotFoundError by default; set notFound: "reply" to send a 404 JSON response directly.
