In documenting the broad strokes of the watermark evaluation Goroutine, it became clear that the field "watermarkRefreshes" while accurate, was unclear. Renamed to be what they contain, stages that have changed, rather than what it's for, which is knowing which stages need a watermark refresh.

Watermark refresh now refers cleanly to the action, rather than the pending action as a result of other work. This should make it a bit easier to follow in the code.

"We evaluate changed stages for watermark advancement with the refreshWatermarks() method." compared to
"We process watermark refreshes in the refreshWatermarks() method."
