 * Boolean URL probe with a timeout — hello-retarget and pending-pod connect.
 *
 * Module-level FUNCTION DECLARATION, not a nested `const` arrow. #2425: the
 * hello path used to close over a `const probeOk` declared ~2000 lines below
 * in the same function; a hello arriving in that window threw
 * `Cannot access 'probeOk' before initialization`, swallowed as an ignored
 * unhandled rejection, so the retarget silently did not happen. A declaration
 * at this scope is initialized before any handler runs, and still hoists if
 * someone later inlines it.
