ci: 拆 e2e batch 最多 6 个 spec，避免 Electron 挂死

之前 batch 2 跑 10 个 spec 经常挂在第 5 个 spec 前后：runner log 显示
Cypress 完全静默 4+ 分钟，到 300s 外层 timeout 被 kill。本地跑同样批
次 60s 就结束，判断是 runner 资源紧张下 Electron 进程内存吃满、主
线程卡死；单次 run 的 spec 数越多越容易触发。

拆成 7 个小 batch（每批 ≤6 spec），单批结束回收 Cypress 进程+浏览
器，避免跨 spec 累积内存压力。同时把 batch 结果汇总从 3 个变量改
成 FAIL flag 里累加，方便扩展。
