/**
 * XuqmGroup Update Service — HarmonyOS hvigorw Release Task
 *
 * HarmonyOS projects use hvigorw (Huawei's Gradle wrapper).
 * This script registers a task compatible with both hvigorw and standard Gradle.
 *
 * Copy to your HarmonyOS module directory and apply:
 *   apply(from = "xuqm_release.gradle.kts")   // in build.gradle.kts
 *
 * Run:
 *   ./hvigorw xuqmRelease --mode project
 *
 * Config: xuqm.properties in the module or project root
 * ---
 * xuqm.serverUrl=https://update.dev.xuqinmin.com
 * xuqm.appId=your-app-id
 * xuqm.apiToken=your-api-token
 * xuqm.storeTargets=HUAWEI          # optional: HUAWEI,HONOR,...
 * xuqm.autoPublishAfterReview=false
 * xuqm.scheduledPublishAt=          # optional ISO datetime
 * xuqm.webhookUrl=                  # optional
 * ---
 *
 * Version is read from AppScope/app.json5 (standard HarmonyOS project layout).
