/**
 * Links the local Swift package apps/mobile/native/VexlNotificationCore into
 * the VexlNSE notification-service extension target created by
 * @bacons/apple-targets. The remote swift-secp256k1 dependency is declared in
 * the package's Package.swift, so Xcode resolves it transitively.
 *
 * IMPORTANT ordering: this plugin must be listed BEFORE '@bacons/apple-targets'
 * in app.config.ts plugins. @expo/config-plugins runs the LAST registered mod
 * action FIRST, so listing this one earlier makes apple-targets' action (which
 * creates the VexlNSE target) execute before this action runs.
