装备鉴定系统：权重随机词条 + 品质分级 + 防重复
-- IdentifySystem.lua-- 核心：权重随机 + 品质分级词条池 + 同类词条防重复

使用示例：
local Identify = require("IdentifySystem")
math.randomseed(os.time())
-- 玩家拾取一把史诗剑，触发鉴定
local affixes = Identify.identify(4)-- 品质4=史诗，4条词条
print("=== 鉴定结果 ===")
for i, a in ipairs(affixes) do
print(i .. ". " .. a.desc)
end
-- 输出示例：
-- 1. 攻击+67
-- 2. 暴击率+4%
-- 3. 吸血+2%
-- 4. 全属性+7
