Before this change, `await io.close();` would resolve before the HTTP server was properly shut down.

Following [1], calling both `io.close()` and `httpServer.close()` would throw an ERR_SERVER_NOT_RUNNING exception, which was not the case before.

This commit fixes `Module '"http"' has no default export.` errors (ts-node + esm).

When using `emitWithAck` with a timeout, if clients didn't respond
and the timeout triggers, the ack callbacks remained in `socket.acks`
Map indefinitely, causing a memory leak.

The uServer (uWebSockets.js) implementation did not emit
"initial_headers" and "headers" events during WebSocket upgrades,
unlike the regular Server which does this via the ws "headers" event.

Since engine.io@6.6.5, the generated .d.ts files import types from "ws"
(WebSocket, PerMessageDeflateOptions), but @types/ws was not declared as
a dependency. This causes TypeScript compilation errors for consumers
who do not have @types/ws installed.

This follows the existing pattern where @types/cors and @types/node are
already listed as dependencies.
