+//  0.1.38 存档根治（最终版）：IndexedDB 持久化后端注入
+//
+//  根因分析（上一版修复遗留问题）：
+//  0.1.38 初版探测 OPFS → 不可用时降级 diskEngine='kv' → AriaEngine 内部
+//  new KVStoreBackend() 不传 medium → KVStore.defaultMedium() 在 OPFS 不可
+//  用时返回 SharedMemoryBackend（纯内存！）→ 数据写入内存 → 进程关闭全丢。
+//  即使 OPFS "假可用"（getDirectory 不抛错但数据不持久化），也有同样问题。
+//
+//  最终方案：
+//  · 自建 IndexedDBBackend（idb-backend.ts），用原生 IndexedDB API 持久化
+//  · MetonaSqlark.create 成功后，通过反射链替换底层 KVStore.medium
+//  · 替换后 reload() 重新从 IndexedDB 加载数据
+//  · 无论 OPFS 是否可用，数据始终写入 IndexedDB（跨进程持久化）
+//  · 保留 OPFS 探测和诊断能力供 UI 展示
