Yggdrasil networking with Ratatoskr

Purpose

Use github.com/voluminor/ratatoskr to embed a Yggdrasil node in a Go application. Ratatoskr provides a userspace gVisor TCP/IP stack, so the application needs no TUN device, root privileges, external Yggdrasil daemon, or yggstack process.

This skill targets the stable Ratatoskr v1 API. The module selected by the user's project is authoritative; bundled API details are a v1.1.0 snapshot.
