/**
 * Build/package Qortal Hub with a platform-native frozen Reticulum binary.
 *
 * Why this wrapper exists:
 * - `rnsd` must be frozen on the same OS/arch as the packaged app.
 * - Cross-packaging a Windows/macOS app from Linux would otherwise embed the wrong
 *   Reticulum binary and break end-user startup.
 *
 * Use the matching host OS for each target, or use the GitHub Actions matrix workflow.
