I don't have the same requirements and when I really thought about it, it turns out I need very few things and can get by without the other requirements.

So for many years it's been orgmode in emacs. Not exactly a wiki, but you can treat it as such. As they are "just text files", you can treat them as that and many things become simpler. Difficult to share with non-emacs users is probably the only downside.
