[Feature Request] <探讨一下dae 改造成oaf上网管控网关的可能性>

### Greetings

参考 https://github.com/Lienol/openwrt-OpenAppFilter
增加一个类似家长控制的功能，限制下游设备访问某应用的时间。
例如每条分流规则，都能设置时间

The issue names no files, tests, or entry points. Start by reading the linked openwrt-OpenAppFilter project and comparing its application-time controls with dae's per-rule routing model. Done means defining and implementing a supported way to restrict downstream access to an application by schedule, with documented behavior and tests.

Written by the indexing model from the issue text.
