Hydration-aware persistence for any reactive store — zero-dep persistSource core; codecs, backends, cross-tab transport, source + framework hydration adapters ship as opt-in recipes

/**
* Mount a `HydrationSignal` into a Svelte `readable` store. Auto-subscribe
* with `$hydratedStore`. Null/undefined signal → a store that stays `true`;
* the subscription is tied to the store's subscriber lifecycle (start on first
* subscriber, unsubscribe on the last). Yields `true` on the server.
*
* @example
* ```ts
* const hydrated = hydratedStore(prefsHydration);
* // {#if !$hydrated}<Skeleton />{:else}<Prefs />{/if}
* ```
