feat(on_action): wire M2 events and add game start metal supplies

Add all new yearly pulse events: metal supply, Feruchemy discovery,
Inquisitor transformation, Ruin's whispers, Hemalurgy discovery,
savant acquisition/consequences. Add duralumin/nicroburst to
compounding check. Add on_imprison hook for late snapping. Grant
starting metal reserves to Allomancers at game start (abundant for
nobles, low for skaa).
