Describe the bug
In the signature of Graph.complementer, the default argument for loops is stated as False, when the default behavior is actually True. (I think the behavior should change to match the signature; in practice I suspect that loops=False is the more common usage.)

To reproduce

import igraph as ig
G = ig.Graph(1)
print(G.complementer().get_edgelist()) #should be the empty list

Version information
Python version 3.12.7, igraph version 1.0.0 installed via pip.
