/**
 * SQL executor type matching Cloudflare's Durable Object sql binding.

 * started routing through `OrchestrationStore.get()`: SQL returned an array
 * but code called `.toArray()` on it, throwing `TypeError`.
 *
 * Verified against the `cloudflare/agents` base class at
 * `packages/agents/src/index.ts:881-888` — `const result = this.sql...`
 * followed by `result.length`/`result[0]` with no `.toArray()` anywhere.
