httptest: synctest support

Worth knowingstdlib

What changed
The net/http/httptest package now supports an in‑memory network implementation for test servers, avoiding port exhaustion and transient networking issues.
Production impact
The source does not say.
Try it
Create a test server with httptest.NewTestServer(t, handler) and observe that it uses an in‑memory network by default.
