I don't think anyone is saying never implement an algorithm. There's a time and place. I've seen code bases where these algorithms had ten different implementations, some of the with subtle bugs, some of them with some performance issues. Your code will also need to be maintained down the line. There's more to software engineering than writing toposort.
Obviously(?) my Boost proposal was made in jest. Anyways, maybe I'm a little bit jealous that you get to do this all the time ;) I just hope I'm not the one that has to maintain it down the road...
If you're doing things in C++ you're already doing very specialized stuff, nobody can advise without actually knowing the app well. Especially if you have an app that rubs in all those different situations.
But... boost seems pretty common. Everyone seems to complain about it, but if it replaces a whole pile of hand written things, it looks like it could really bring some consistency to a project. I've never done serious C++ outside of embedded though, so I don't have Boost experience.
In a dynamic language like JS, you'd search for "Graph theory algorithms library" and probably find one with ten million downloads, investigate the maintainer a bit, and use it.

Left-pad was as far as I know written by one person. Had they used underscore or lodash or any of those bazillions of utility libraries out there, that have real code review, and are actually making money, this would be way less likely.
That's why I'd look for a graph algorithms library first, not a topo sort specifically, I'd be looking for larger one size fits all libs likely to be maintained by a larger group and have more eyeballs on them.
