-Minimal, dependency-light wrapper around the HTTP Gateway.

-Usage:
-
-```bash
-npm i
-export GATEWAY_BASE_URL=http://127.0.0.1:6001
-export GATEWAY_API_KEY=your_api_key
-```
-
-```ts
-import { GatewayClient } from './src/client';
-
-const c = new GatewayClient(process.env.GATEWAY_BASE_URL!, process.env.GATEWAY_API_KEY!);
-await c.createTable('CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT)');
-await c.transaction([
-  'INSERT INTO users (id,name) VALUES (1,\'Alice\')'
