/**
 * #3507 — the home Provider Topology pulse was dead because activeRequests was
 * hardcoded to [].  Fix: map the in-flight LiveRequest entries (pending/running)
 * from useLiveRequests to the { provider, model }[] shape expected by
 * <ProviderTopology>.
 *
 * selectActiveRequests() is a pure mapping function — no React required.
