Classification band distribution over a lookback window

Server-side aggregation over the last N days of Alternative.me Fear & Greed Index observations. Returns one count per classification band (Extreme Fear, Fear, Neutral, Greed, Extreme Greed), the arithmetic mean of the raw 0-100 value, and the inclusive period bounds. Useful for monitoring regime shifts without processing the full series.
