comment Does little-o notation imply going into infinity?
What I meant is that not only f(n) >= g(n) for some n, but f(n)=M so that g(n)<=M and g(x)<=M for all x.

I've updated the question. I hope I'm not too confused.

comment Proving that a formula cannot be proven (has no formal proof) in a given deduction system
What does "different semantics" mean for, say, the Hilbert system? For example, will redefining $\to$ to have a different truth table mean "different semantics"?

Yes, $\square P \equiv \neg \lozenge \neg P$ -- which also leads me towards trusting my conclusion.
