Architecture

Xasu/                    ← SwiftUI app (HomeView, SettingsView)
  Core/VPN/VPNManager    ← manages NETunnelProviderManager
XasuTunnel/              ← Network Extension
  PacketTunnelProvider   ← starts byedpi SOCKS5 + PAC proxy settings

Traffic flow:

iOS App → System Proxy (PAC) → byedpi SOCKS5 (127.0.0.1:10800) → Internet

byedpi applies TCP Split on TLS ClientHello to bypass DPI at the ISP level.
