Combat: ability archetype byte (MC-6 dispatch spike)

byte Archetype on AbilityDefBlob (AbilityArchetype enum: Projectile/Hitscan/Cone/Aoe), authored on AbilityDefinition + baked in AbilityDatabaseAuthoring, read at dispatch in AbilityFireSystem -- NOT folded through EffectiveAbilityStats/StatRecomputeSystem (static identity, not a tunable stat; MC-4 review BURST-1). All current abilities are Projectile (0) -> zero behaviour change; the dispatch read-point is the de-risk spike for MC-6 hitscan/cone/aoe.
