============ SmoothingETA

SmoothingETA estimates remaining time via a recency-weighted rate.

Reach for it when per-item timing is noisy but you still want a stable estimate without the fixed sample window AdaptiveETA uses. The exponential moving average weights recent updates more than old ones without discarding history outright, and smoothing_algorithm with smoothing_parameters picks the algorithm. In the demo, each step's timing carries random jitter, yet the countdown moves smoothly.
