// Tiny localhost HTTP server for qmltest fixtures. Listens on a free
// ephemeral port; for any incoming request, captures the request line +
// headers and replies with a fixed JSON body. Exposed to QML as the
// `TestHttpServer` element so tests can instantiate one inline:
//
//   TestHttpServer {
//       id: srv
//       responseBody: '[{"id":"1","title":"a","done":false}]'
//   }
//   ReactiveListModel { baseUrl: srv.url; ... }
//   compare(srv.lastAuthHeader, "Bearer testtoken")
//
// Just enough HTTP to serve a single line-of-sight request — no
// chunked encoding, no keepalive, no Content-Length parsing on the
// way in. The framework's network paths only ever issue GET /…
// against this stub during the test, so that's all we need.
//
// `apiGetCount` counts only requests under `/api/…` so tests can
// distinguish the model's HTTP fetches from Mercure's SSE reconnect
// attempts (which hit `/.well-known/mercure`).
