To clarify the
intention of Tyrfang, and to provide official answers:

1) Can Tyrfang be drawn at all before the 12 ticks is over?
No.

2) When does the 12 tick count start? At the beginning of the scene or on my first move?
On your first move. Yes, this means a poor initiative roll can be extremely painful.

3) If Tyrfang cannot be drawn, can the following be done without a weapon in hand?
Total defense?
Distract other?
Provide tactical for another?
Defensive stance bonus for yourself?
Total defense: Yes. Tyrfang will not prevent you from defending yourself to the best of your ability so long as you are unarmed while doing so, and nothing in Total Defense requires you to have a weapon drawn to do so.
Distract Other: No. This can be interpreted (and is, by Tyrfang) as an offensive action.
Provide Tactical Edge: No. Same as distract other.
Defensive Stance bonus: No. The Talent states that you are suffering a penalty to attack rolls in exchange for a bonus to Avoidance. A stance is by definition an offensive action (even if the talent is called "Defensive Stance").
That said, I agree with most of your interpretations: You may heal, buff your allies (so long as no damage or harmful effects are done to your foes), and challenge (with all the risks that entails).
However, Tyrfang will not differentiate between foes. Mindless, bestial, undead, intelligent, hyper-intelligent, etc... are treated all the same to this sword. You do not know that something cannot understand you; only that it does not appear to understand you. Tyrfang has its own Code of Honour, which includes treating all potential foes the same, and mindless or otherwise it will not allow *anything* to be slain if it can prevent it.
As far as convincing a wolf to surrender, I point you to the idea of using Beast Lore (Ch) instead of Persuasion. But that's neither here nor there for the purposes of this discussion. The point is that Tyrfang requires you to make your best effort to convince your foe to stand down.
