// TestDefaultControlPlaneIdleTimeout pins the control-plane idle-timeout
// default. The value is a product decision, not an implementation detail: it
// decides whether a client that pauses between statements keeps its connection.
//
// At 60s it did not. A batch client spreading its DAG over parallel
// connections idles one whenever a thread waits on work elsewhere, so the
// control plane closed it and the client reported a lost connection on its
// next statement. A client cannot safely replay a write that may already have
// committed, so that surfaced as a failed run rather than a reconnect.
