The variant has on the left-hand side the topologically sorted vector and the right-hand side is a pair showing the path and its parent that represent a cycle in the graph making the sort impossible. This change prepares for enhanced cycle error messages that can provide more context about the cycle. The variant approach allows callers to handle cycles more flexibly, enabling better error reporting that shows the full cycle path and which files are involved. Adapted from Lix commit f7871fcb5.
