【框架设计】装备分解：分解产出与材料回收链

---NPC 分解：按品质产出矿石材料
function Decompose.run(actor, makeIndex)
    local item = Decompose.locate(actor, makeIndex)
    if not item then
        sendmsg(actor, 1, "物品不存在或已失效")
        return false
    end
    local bind = checkitemstate(item, 1)
    -- 按品质定产出档：白 2 份 蓝装 3 份 绿装 4 份
    local tier = Decompose.tierOf(item)
    local count = 1 + tier
    delitembymakeindex(actor, makeIndex)
    giveitem(actor, "黑铁矿石", count)
    if bind == 1 then
        Decompose.markBind(actor)
        sendmsg(actor, 1, "绑定装备分解产出为绑定材料")
    end
    sendmsg(actor, 1, "分解成功，获得黑铁矿石 x" .. count)
    return true
end

---合成：5 份低纯矿合 1 份高纯矿
function Decompose.compose(actor, fromName, toName)
    local need = 5
    if not checkitemw(actor, fromName, need) then
        sendmsg(actor, 1, "材料不足，需要 " .. fromName .. " x" .. need)
        return false
    end
    takeitem(actor, fromName, need, 0, "合成消耗")
    giveitem(actor, toName, 1)
    sendmsg(actor, 1, "合成成功：" .. toName .. " x1")
    return true
end
