feat: add live ride status via Queue-Times.com API

Park detail pages now show real-time ride open/closed status and wait
times sourced from Queue-Times.com (updates every 5 min) when a park
is operating. Falls back to the Six Flags schedule API for off-hours
or parks without a Queue-Times mapping.

- lib/queue-times-map.ts: maps all 24 park IDs to Queue-Times park IDs
- lib/scrapers/queuetimes.ts: fetches and parses queue_times.json with
  5-minute ISR cache; returns LiveRidesResult with isOpen + waitMinutes
- app/park/[id]/page.tsx: tries Queue-Times first; renders LiveRideList
  with Live badge and per-ride wait times; falls back to RideList for
  schedule data when live data is unavailable
- README: documents two-tier ride status approach
