Problem

A monitoring service buffers raw metric samples in `nums`, and the dashboard smooths the jitter by reporting the mean of each run of `k` consecutive samples, each value rounded to two decimals. Return one average per window, in sample order. When there are fewer than `k` samples there is nothing to smooth, so return an empty list.

Summary

Turn a jittery stream into a calm read, one step at a time.
