Problem

A round-robin scheduler keeps its consumers in a fixed order and advances the assignment by `shift` slots each cycle so the load spreads evenly down the line. Given the `consumers` list and a `shift`, return the order rotated to the right by `shift`, so the last `shift` consumers wrap around to the front. The `shift` can exceed the roster length or be negative (a left rotation), and an empty roster comes back empty.

Summary

Load has to keep moving. Pass it down the line.
