Summary

Fixes #59
/claim #59

Problem

dumpDatabaseRoute in src/export/dump.ts previously executed SELECT * FROM ${table}; for every table and concatenated the entire SQL dump in memory into a single dumpContent string before wrapping it in new Blob([dumpContent]). On large Cloudflare Durable Object SQLite databases, this exceeds Worker memory/response limits and fails.

Solution

• Added fetchRowsBatches(tableName, dataSource, config) async generator querying SELECT * FROM ${tableName} LIMIT 1000 OFFSET ${offset}; in batches of ROW_BATCH_SIZE = 1000.
• Streamed table schemas and batched INSERT INTO statements through a ReadableStream<Uint8Array> directly into new Response(stream, { headers }) so memory usage remains bounded regardless of database size.
