The current implementation of the topological sort algorithm relies on a recursive function. This causes stack overflow issues when the graphs are very large. There is also a performance issue in the current implementation related to the way std::find() is being used. This commit reimplements the topological sort algorithm to fix these issues: - Uses an iterative approach instead of recursive. - Removes the use of std::find() and instead relies on keeping the state with a helper variable. - Reimplements the cycle checking algorithm to use the same topological sort function as the one used during scheduling. - Fixes a bug with make_edge() not removing the dest node from the list of root nodes.
