start-backtest.ts

// Submit a 30-day backtest, then poll the status until it finishes.
// Backtests are async on the server side — `create` returns immediately
// with a backtest ID; you poll `get` to see when it completes.
//
// Run: npx tsx start-backtest.ts <hopper-id>
//
// Backtests are subject to the `backtest` rate bucket (separate from the
// normal request bucket). The SDK retries automatically on 429; if you
// see RATE_LIMITED here you've hit your daily quota — check
// `client.backtest.limits()` to see how many you have left.
