【策划架构】Lua键名压缩：裁决之杖同步串的字典瘦身

local function pack(item)
    return "durability=" .. item.dur
        .. ",attack=" .. item.atk     -- 长键直拼，28字符
end

local DICT = {d = "durability", a = "attack"}
local function pack(item)
    return "d=" .. item.dur .. ",a=" .. item.atk
end
local function unpack(str)
    local out = {}
    for k, v in string.gmatch(str, "(%a)=(%d+)") do
        out[DICT[k]] = tonumber(v)    -- 查字典还原长键
    end
    return out
end
