【性能调优】条件分支的排序：高频路径前置的微小优化

---攻击判定的分支：按发生概率排序
function Attack.resolve(actor, target)
    -- 90% 的攻击走普通命中：放最前
    local roll = math.random(1, 100)
    if roll <= 90 then
        return Attack.normal(actor, target)
    elseif roll <= 97 then
        return Attack.crit(actor, target)      -- 7% 暴击
    elseif roll <= 99 then
        return Attack.miss(actor, target)      -- 2% 未命中
    end
    return Attack.blocked(actor, target)       -- 1% 格挡
end

---相邻分支的合并：减少判断的层级
function Damage.typeOf(actor, target)
    -- 三个同处理的条件合并为一个区间判断
    local t = target.type
    if t == 'monster' or t == 'summon' or t == 'pet' then
        return 'pve'
    end
    return 'pvp'
end

---改写：查表替代分支链
local PVE_TYPES = { monster = true, summon = true, pet = true }
function Damage.typeOfFast(target)
    if PVE_TYPES[target.type] then return 'pve' end
    return 'pvp'
end
