Guard undoMove against empty history

Calling undoMove() when no prior move was pushed (for example immediately after setFEN() or after one extra undo) now reaches history.back()/pop_back() on an empty vector, which is undefined behavior and can crash in debug/test runs. The removed assert(!history.empty()) was the only local guard here, so this commit regresses fail-fast behavior into memory-unsafe behavior for a publicly callable method.
