The homepage was flagging every park as weather delay because calendar.ts
collapsed "fetchLiveRides returned null" into the same openRides=0 bucket as
"all rides actually closed." Meanwhile every scraper (queuetimes, sixflags
operating-hours, sixflags wait-times) was swallowing non-OK responses and
exceptions silently, so logs gave no signal which upstream was failing or how.
Add a small scraperWarn helper that emits in the same shape as backend/log.ts
(without importing it — lib/scrapers is shared with the Next frontend). Use it
in all three scrapers to record HTTP status and error name+message before each
return null. Add parksSkipped to the tier-5 summary log so we can tell when the
openParks filter is rejecting everyone vs the fetcher silently failing.
Convert calendar.ts ridesCache to a discriminated union { kind: "ok" | "unknown" }.
Weather delay only fires on { kind: "ok", openRides: 0 }; unknown entries get
a 30s TTL so we recover quickly when upstream comes back and don't thunder-herd
in the meantime.

Three usability fixes after a day of using the ride detail page.
1. Six Flags is now the primary source for regular wait times. SF's
/wait-times endpoint reports regular waits alongside Fast Lane, and it
updates more promptly than Queue-Times around park-open. The sampler
and the live /rides + ride-history routes all prefer SF's regularWaittime
when its createdDateTime is non-empty; Queue-Times remains the fallback
and the authoritative isOpen source.
2. The today chart's Fast Lane line now stays visible when its value is 0
(walk-on). Y-axis bottom padding ensures the line sits clearly above the
X-axis frame instead of being clipped against it. The tooltip shows
"walk-on" instead of "0 min" for that case.
3. Outages are now explicit on the chart instead of just being gaps.
computeOutages walks today's samples to find contiguous closed runs and
numbers them chronologically. Each outage renders as a translucent pink
ReferenceArea with a "#N" label. The custom tooltip detects when the
cursor is over an outage span and shows "Outage #N — Hh Mm" (e.g.
"Outage #2 — 1h 28m") in place of the wait/Fast Lane rows.
Includes a seed-test-samples.ts dev script for eyeballing the chart with
synthetic outage data.

Join Fast Lane waits from the Six Flags /wait-times endpoint onto
Queue-Times rides by name. A new toggle on the live ride panel swaps
the shown wait to the Fast Lane number; regular waits and open status
still come from Queue-Times.
