/**
 * The router's half of single-flight collection: runs the matched routes'

 * hands the loaded router to `collect`. This is the cache-agnostic
 * trigger — the router knows how to load route data for a target, and
 * deliberately not what that data was written into. Any cache builds a
 * flight-data hook from it by composing its own extraction:
 *
 * ```ts
 * registerFlightDataSource('sq', (event, outcome) =>
 *   loadFlightTarget({
 *     router: createAppRouter((queryClient = createQueryClient())),
 *     event,
 *     outcome,
 *     collect: () => dehydrate(queryClient),
 *   }),
 * )
 * ```
 *
 * The load observes post-mutation state: the flight event's request
 * targets `outcome.targetUrl` with the mutation's cookie effects already
 * folded in (a session the mutation just wrote or cleared is what the
 * data functions see, exactly as the browser's next request would), and
 * the router is pointed at the target through a fresh memory history.
 * Resolves undefined when there is no target (a non-browser caller, or a
 * redirect leaving the app).
