/**
 * Bun-native SQLite storage backend.
 *
 * Uses bun:sqlite (built into Bun, zero deps). Same schema and behavior as
 * TradingSqliteBackend but with Bun's SQLite API instead of better-sqlite3.
 *
 * Usage:
 *   import { BunSqliteBackend } from 'polynode-sdk';
 *   const trader = new PolyNodeTrader({ storage: new BunSqliteBackend('./trading.db') });
