Poll for market open instead of single long setTimeout

Browse Source 
macOS sleep suspends the Docker VM, causing long setTimeout calls to
never fire. Replace the one-shot wait with a polling loop that checks
getClock every 30s (capped to time-until-open), so the bot resumes
promptly after the host wakes.
