/**
 * `@noy-db/hub/history` — subpath export for record-history / diff /
 * ledger-based audit trail + point-in-time primitives.
 *
 * Solo apps that don't track versioning, don't need a hash-chained
 * audit log, and don't restore to earlier points in time can exclude
 * this entire surface. Bundle savings ~1,880 LOC.
 *
 * The strategy seam is `withHistory()` — pass the returned
 * strategy to `createNoydb({ historyStrategy: ... })`. Without it,
 * the core `NO_HISTORY` stub no-ops snapshots/prune/clear and throws
 * on read APIs (`history`, `getVersion`, `diff`, `vault.at`,
 * `vault.ledger`).
 *
 * Named re-exports (not `export *`) so tsup keeps the barrel
 * populated even with `sideEffects: false`.
