Add XMLHttpRequest.timeout with curl enforcement

Implement the XHR timeout property end-to-end: the JS-visible getter/setter stores the value, send() passes it to the HTTP client, and curl enforces it via CURLOPT_TIMEOUT_MS. On timeout, a `timeout` event is dispatched instead of `error`, per the XHR spec.
