How to augment `proccess.env` as well from `createEnv` output.

i dont think this is possible, as the error suggests it creates a circular reference.

what's the use case why you wanna do this? I believe augmenting process.env here is kinda scary since we have no assurance if the type iss correct then considering transforms, default values etc aren't taken into account then.

e.g.:

export const env = createEnv({
  server: {
    DATABASE_URL: z.string().url().default("mysql://localhost:3306/db"),
  },
  runtimeEnv: {
    DATABASE_URL: process.env.DATABASE_URL,
  },
});

here env.DATABASE_URL will be guaranteed to be a string, but process.env.DATABASE_URL can be undefined. augmenting the type would potentailly cause a runtime error
