Medium and low priority tiers were generating full static date ranges
(150 and 185 dates) every day. With a queue limit of 200, high (31) +
medium (150) consumed the entire budget, leaving only ~19 slots for low
priority — causing the observed ~6 month cap.
Medium now selects the 60 oldest-scraped (or never-scraped) dates from
the days 31-180 window; low selects the 30 oldest from days 181-365.
Per-run budget drops from ~365 to ~121 dates, and coverage naturally
cycles through the full year: medium every ~2-3 days, low every ~6-7 days.
