Module export 

Export and Import functionality for SQLite databases

This module provides conversion between IndexedDB block storage and standard SQLite .db files.

Features

• Export: Convert IndexedDB blocks to downloadable .db file
• Import: Load .db file into IndexedDB storage
• Validation: Verify SQLite file format integrity

Architecture

The system works with 4096-byte blocks stored in IndexedDB. Export reads all allocated blocks and concatenates them into a standard SQLite file. Import splits a .db file into blocks and writes them to IndexedDB with proper metadata tracking.
