Request Session Combinators: `tapAll` and `mapAll`

const route = makeRequestSession(request.headers.get("cookie") ?? "").pipe(
  Effect.andThen(self),
  Effect.tapBoth({
    onFailure: () => setSession(headers),
    onSuccess: () => setSession(headers),
  }),
  Effect.mapBoth({
    onSuccess: Remix.Result({ headers }),
    onFailure: Remix.Result({ headers }),
  }),
  Effect.withSpan(`${request.method} ${url.pathname}`, {
    attributes: {
      url: request.url,
      method: request.method,
    },
  }),
);
