Subject: [PATCH] Reset DefaultResolver on Android CGO builds

v2ray-core hardcodes 8.8.8.8 as the system DNS on all Android builds
(v2fly/v2ray-core#572). That is only needed without CGO; with CGO it
causes DNS loopback/poisoning under Android VPN protect
(shadowsocks/v2ray-plugin-android#44).

Upstream fixed this with a build tag in v5.52.0 (v2fly/v2ray-core#3755),
which requires Go 1.25.5+. Until we can bump core, undo the override
from main after dependency package inits run.
