Slice 2 (WIP): class data layer + melee-augment routing

Foundation for Two Classes (DR-037). New ids (CharacterId.Warrior/Ranger,
AbilityId.WarriorCone, StatTarget.MeleeDamage/MeleeRange); CharacterStatsRef.Id ->
[GhostField] so the owning client folds the right class stats; MeleeComboSystem
folds per-player MeleeDamage/MeleeRange off the replicated StatModifier buffer
(HasBuffer-guarded -> identity without class seeds, so behavior-preserving).
345/345 EditMode. Slice 2 design review + locked forks logged in the session note.
