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

/**
 * Build an IndexedDB-backed `PersistStorage` (via idb-keyval) —
 * **structured-clone mode**: IndexedDB stores the `StorageValue` envelope
 * NATIVELY, so `Set` / `Map` / `Date` round-trip via the structured-clone
 * algorithm with zero (de)serialization — no seroval, no JSON, and better
 * DevTools inspection (objects, not encoded strings). The payoff of the
 * generic wire-type seam (`StateStorage<TRaw>`).
 *
 * Codec use cases (encryption at rest, compression, legacy string payloads)
 * are a one-line composition over the core primitives instead of a second
 * factory:
 *
 * ```ts
 * createStorage(() => idbStateStorage(store), myEncryptedCodec, options);
 * ```
 *
 * Semantics vs `localStorage` backends:
 * hydration can't settle before first paint, so `useHydrated` gating is
 * mandatory rather than optional; IndexedDB fires no `storage` events, so
 * `crossTab` needs a `BroadcastChannel` bridge via `crossTabEventTarget`;
 * and `clearCorruptOnFailure` is inert here — the identity decode never
 * throws (structured clone can't truncate-corrupt the way strings can).
 *
 * @example
 * ```ts
 * import { createIdbStorage } from "@stainless-code/persist/backends/idb";
 *
 * const storage = createIdbStorage<Prefs>(); // Set/Map/Date just work
 * ```
