Problem

A monitoring service records maintenance windows as `[start, end]` minute offsets in `windows`, arriving in no particular order and often overlapping or fully containing one another. Collapse them into the fewest non-overlapping windows that cover the same time, where two windows that touch at an endpoint count as one continuous window. Return the windows ordered earliest first.

Summary

Overlapping outages hide how much time is really dark. Collapse them into the truth.
