+Add Edge/Cloudflare Workers support for @voltagent/libsql
+
+- New `@voltagent/libsql/edge` export for edge runtimes
+- Refactored adapters into core classes with dependency injection
+- Edge adapters use `@libsql/client/web` for fetch-based transport
+- Core uses DataView/ArrayBuffer for cross-platform compatibility
+- Node.js adapters override with Buffer for better performance
+
+Usage:
+
+```typescript
+import { LibSQLMemoryAdapter } from "@voltagent/libsql/edge";
+
+const adapter = new LibSQLMemoryAdapter({
+  url: "libsql://your-db.turso.io",
+  authToken: "your-token",
+});
+```

+/**
+ * Edge/Cloudflare Workers entrypoint for @voltagent/libsql
+ *
+ * This module provides edge-compatible adapters that work with Cloudflare Workers,
+ * Vercel Edge Functions, and other edge runtimes.
+ *
+ * Key differences from the main entrypoint:
+ * - Uses @libsql/client/web instead of @libsql/client
+ * - Only supports remote Turso URLs (libsql://)
+ * - No file system operations (no local SQLite support)
+ *
+ * Usage:
+ * ```typescript
+ * import { LibSQLMemoryAdapter } from "@voltagent/libsql/edge";
+ *
+ * const adapter = new LibSQLMemoryAdapter({
+ *   url: "libsql://your-db.turso.io",
+ *   authToken: "your-token",
+ * });
+ * ```
