【后端接口】行会仓库：共享存取与流水审计

---存入：职位校验后入库
function GuildRepo.deposit(actor, makeIndex)
    local pos = getplayvar(actor, 2, "GuildPos")
    if pos == nil or pos == "" then
        sendmsg(actor, 1, "加入行会后才能使用仓库")
        return false
    end
    local item = Repo.locate(actor, makeIndex)
    if not item then return false end
    if Repo.count() >= 200 then
        sendmsg(actor, 1, "仓库已满 200 格")
        return false
    end
    delitembymakeindex(actor, makeIndex)
    Repo.add(item)
    Repo.log(actor:GetName(), "存入", item:GetName())
    sendmsg(actor, 1, "已存入 " .. item:GetName())
    return true
end

---取出的双重校验与流水
function GuildRepo.withdraw(actor, repoIdx)
    local pos = getplayvar(actor, 2, "GuildPos")
    if pos ~= "leader" and pos ~= "vice" then
        sendmsg(actor, 1, "职位不足，无法取出")
        return false
    end
    local item = Repo.peek(repoIdx)
    if not item then return false end
    if not giveitem(actor, item:GetName(), 1) then
        sendmsg(actor, 1, "背包已满")
        return false
    end
    Repo.remove(repoIdx)
    Repo.log(actor:GetName(), "取出", item:GetName())
    sendmsg(actor, 2, actor:GetName() .. " 从行会仓库取出了 " ..
        item:GetName())
    return true
end
