 * Dead-man's switch: place a resting limit, then schedule cancel-all after 10s.
 * Hyperliquid only enables this after $1M traded volume; the example still
 * places and cancels the limit so the order path is exercised either way.

 * Unix:
 * HYPERLIQUID_PRIVATE_KEY='0xabc' npx tsx examples/Rest/rest-schedule-cancel.ts
