Expand README with desktop platform requirements (Windows x86, macOS ARM), helper build commands, gateway utility scripts, and updated local test flow. Add realistic MVP usage section clarifying current platform build status, gateway configuration needs, and admin debug profile behavior with client private key handling.
Bundle the macOS ARM NexaVPN tunnel helper here. Expected filename: - nexavpn-tunnel-helper This helper encapsulates the WireGuard runtime so the end user only interacts with NexaVPN.
