Add useRequest for one-shot RPC reads#1618

`useRequest(source)` fires a request on mount and re-fires whenever the source identity changes. The source is any `ReactiveActionSource<T>` (the `{ reactiveStore() }` duck-type) — `PendingRpcRequest` is the canonical implementation. Memoize the source with `useMemo` keyed on its inputs; `react-hooks/exhaustive-deps` then catches stale closures by default. Pass `null` to disable the request.
The hook returns `{ data, error, isLoading, refresh, status }`. Status is one of `loading | loaded | error | retrying | disabled`. `refresh()` dispatches on the same underlying action store, so its built-in stale-while-revalidate keeps `data` populated and reports `retrying` during the next attempt — the bridge doesn't need to mirror state externally.
Optional `perRequestSignal: () => AbortSignal` is invoked on every dispatch (initial fire + every `refresh()`). The returned signal is passed through to `.reactiveStore({ perRequestSignal })`. The natural use is per-attempt timeouts (`() => AbortSignal.timeout(5_000)`), which reset on refresh. The factory is held in a ref synced to the latest render — inline closures are fine.
Disabling and unmount cancellation are handled the React-native way: pass `null` for the source (result reports `disabled`), or let the component unmount (effect cleanup aborts the in-flight call). There's no hook-level kill switch — adding one would just duplicate React's lifecycle.
Lifts the `useIsomorphicLayoutEffect` helper that was duplicated in `useAction.ts` into a shared internal module so both hooks (and forthcoming ones) share a single definition.
Exports `RequestResult<T>` and `UseRequestOptions` for plugin hooks that build on this surface.
