Export `AdapterMeta` for `toNodeHandler` and `toFetchHandler` in Node.js

[alpheusmtx]

Describe the feature

While adding types to variable assigned with toNodeHandler and toFetchHandler, AdapterMeta is missing:

import type { Express } from "express";
import type { 
    FetchHandler, 
    NodeHttpHandler,
    AdapterMeta, // missing
} from "srvx";
import type { AdapterMeta } from "srvx/node"; // missing

import express from "express";
import { toFetchHandler, toNodeHandler } from "srvx/node";

const app: Express = express();

const fetchHandler: FetchHandler & AdapterMeta = toFetchHandler(app);

const nodeHandler: NodeHttpHandler & AdapterMeta = toNodeHandler(fetchHandler);

Can you little explain why you need custom type annotation with adapter meta?

PR welcome.

PR welcome.

For a cleaner variable type recognition.

// with this I have to click into the function to check the returned type.
const fetchHandler = toFetchHandler(app);

// with this I can directly click into the type and see what it returns.
const fetchHandler: FetchHandler & AdapterMeta = toFetchHandler(app);
