【框架设计】觉醒系统：觉醒等级与技能进化条件

---觉醒升级：消耗觉醒石，纯堆料必定成功
function Awaken.upgrade(actor)
    local lv = tonumber(getplayvar(actor, 2, "AwakenLv")) or 0
    if lv >= 10 then
        sendmsg(actor, 1, "已达觉醒上限")
        return false
    end
    local cost = (lv + 1) * 5
    if not checkitemw(actor, "觉醒石", cost) then
        sendmsg(actor, 1, "觉醒石不足，需要 " .. cost .. " 枚")
        return false
    end
    takeitem(actor, "觉醒石", cost, 0, "觉醒消耗")
    setplayvar(actor, "HUMAN", "AwakenLv", lv + 1, 1)
    sendmsg(actor, 1, "觉醒等级提升至 " .. (lv + 1) .. " 级")
    return true
end

---技能进化：觉醒等级达标后进化指定技能
local EVOLVE = {
    ["烈火剑法"] = { needLv = 3, newId = "烈火剑法·焚天" },
    ["施毒术"]   = { needLv = 5, newId = "施毒术·蔓延" },
}

function Awaken.evolve(actor, skillName)
    local cfg = EVOLVE[skillName]
    if not cfg then return false, "该技能不可进化" end
    local lv = tonumber(getplayvar(actor, 2, "AwakenLv")) or 0
    if lv < cfg.needLv then
        sendmsg(actor, 1, "觉醒 " .. cfg.needLv .. " 级后可进化")
        return false
    end
    local oldId = getskillindex(skillName)
    local newId = getskillindex(cfg.newId)
    delskill(actor, oldId)
    addskill(actor, newId)
    QF_Broadcast(actor:GetName() .. " 的 " .. skillName .. " 觉醒进化！")
    return true
end
