Problem

A status display cycles through a fixed ring of items, and you need to advance its starting point by `k` slots so the item currently sitting `k` places along becomes the new front. Return a fresh list holding that left rotation, where `k` may be zero, larger than the length of `lst`, or negative (a negative `k` shifts the ring the other way). An empty `lst` comes back empty.

Summary

Keep moving, same ride.
