instant992 8e79f2ee9c FoxiGram: Telegram client with built-in Xray VLESS proxy
Based on Nekogram. Key additions:
- Rebrand to FoxiGram (app name, APK name, applicationId com.foxigram.app)
- Embedded Xray (VLESS+Reality) proxy client via JNI libxray.so
- Bundled hidden one-tap proxies (LTE + WiFi), read-only in UI
- Auto-restore proxy on restart, rebind to active network (LTE/WiFi)
- Server credentials externalized to git-ignored XrayServers.java (+ template)
- libxray Go source included; compiled .so, keystore, google-services.json ignored
