Implement Virtual VPN in i2pd-Android to Proxy Selected App Traffic Including DNS

[ghost]

I would like to have a feature in i2pd-android that sets up a virtual VPN to proxy the traffic of selected applications through I2P, including DNS requests. I've tried using socktun and sing-box, but I'm unsure how to proxy DNS queries with them. Could you provide guidance on how to achieve this or consider adding this functionality?
