大幅降低前后端的内存泄露

 - 请确认无课程时间冲突
 - 请确认剩余学分足够
 - 请确保网络环境流畅 (不要去人多的地方)
-- 请提前两三分钟开启抢课模式
+- 抢课时, 请提前两三分钟开启抢课模式; **抢课模式下没有重启机制, 由于 `Playwright` 的特性, 消耗内存会逐渐增加, 提前开启太久可能会导致内存不足** (蹲课模式下浏览器会定期重启, 没有这个问题)
 - 其他年级抢课开始前后, 教务系统会显示账号已锁定, 与小鸦抢课无关!
 - **据传, 选课系统同时只支持约三/四/五（说法不一）个页面同时操作, 小鸦抢课会为每门课都打开一个页面 (`单线程蹲课` 模式除外), 所以如果要同时选多门课, 请自行承担风险** (但是我这边测试的时候, 排除了上面说的其他年级抢课的影响, 同时多线程蹲六门课也是正常的, 不知道到底有没有限制)
 - 成功率不是百分之百, 请手动二次确认选课结果; 同时, 千万不要将本软件作为唯一的选课手段!
