【后端接口】组队招募板：队伍撮合与自动匹配

---队长挂单：队伍配置上招募板
function TeamBoard.publish(actor, needJob, minLevel)
    local player = class(actor)
    if not player then return false end
    -- 队长身份校验
    if not Team.isLeader(actor) then
        sendmsg(actor, 1, "只有队长可以挂出招募")
        return false
    end
    local vacancy = 6 - Team.sizeOf(actor)
    if vacancy <= 0 then
        sendmsg(actor, 1, "队伍已满员")
        return false
    end
    TeamBoard.list[actor] = {
        needJob = needJob, minLevel = minLevel,
        map = actor.mapId, at = os.time(),
    }
    sendmsg(actor, 1, "招募已挂出，缺 " .. vacancy ..
        " 人，需求职业：" .. needJob)
    return true
end

---散人报名：条件比对与自动入队
function TeamBoard.apply(actor, boardId)
    local player = class(actor)
    if not player then return false end
    local board = TeamBoard.list[boardId]
    if not board then
        sendmsg(actor, 1, "该招募已结束")
        return false
    end
    if actor:GetLevel() < board.minLevel then
        sendmsg(actor, 1, "等级不足，需 " .. board.minLevel .. " 级")
        return false
    end
    if board.needJob ~= "any"
        and getplayvar(actor, 2, "Job") ~= board.needJob then
        sendmsg(actor, 1, "需求职业为 " .. board.needJob)
        return false
    end
    invitegroup(actor)
    sendmsg(actor, 1, "报名成功，等待队长确认")
    TeamBoard.list[boardId] = nil
    return true
end
