/**
 * G-code Explorer - ncSender plugin
 * Entry for the Node-based ncSender platforms (v1 / pro-v1).
 *
 * The plugin's actual logic lives in commands.js, which is written to
 * run inside the pro-v2 (C#) embedded JS engine where a global
 * `pluginContext` is injected. This wrapper adapts the v1 `ctx` API to
 * that contract so both platforms share one implementation.
