fix(aliases): handle cycle detection in dependency graph

Add NetworkXUnfeasible to exception handling in select_aliases()
when sorting aliases topologically. Cycles or graph issues now
fall back to unordered list instead of crashing.

Fixes describe_aliases(with_dependencies=True) crash when
alias graph contains cycles or broken references.
