fetchium@0.4.3

Patch Changes

• e395061: Fix TopicQuery subscribe/unsubscribe to track consumer-read lifecycle instead of the fetch path. Previously, subscribe never fired when send() short-circuited (pre-fulfilled topic via fulfillTopic, or cache within staleTime), but the consumer's unmount would still call unsubscribe and tear down adapter state that was never registered.
• c35eee2: Fix useQuery to stabilize thunk identity across re-renders. Without it, signalium allocated a new signal per render, which under some React commit orderings (React 18 / React Native) caused a spurious getConfig.subscribe cleanup while the consumer was still mounted.
