feat(triggers): add hemalurgy trigger and redirect snapping effect

Add has_multiple_spikes_trigger for Inquisitor transformation check
(requires 3+ spike traits). Redirect trigger_snapping_effect to use
the snapping event chain (mistborn_snapping.0020) as single source
of truth for Misting type assignment, replacing inline duplication.

Fix minor formatting issue in trait_misting_coinshot definition.
