--- Регистрирует вклад в `modifier_stats_multiplier`.
-- - `kind === "attributes"` (по умолчанию): сумма % умножается на **базовые** Str/Agi/Int и даёт бонус к соответствующему атрибуту (карты).
-- - `all_stats_pct`: тот же % к **каждой** базовой характеристике Str/Agi/Int (арсенал).
-- - `strength_pct` / `agility_pct` / `intellect_pct`: % только к **базовому** Str/Agi/Int (арсенал).
-- - Остальные `kind`: сумма идёт в соответствующий `ModifierFunction` (исходящий/входящий урон, AS%/MS%, урон от базы атаки) — арсенал;
--   для `incoming_damage_reduction_pct` сумма **не** добавляется линейно в движок, а сжимается формулой с убыванием (см. `incoming_damage_reduction_combine`).
