# CI 专用: 为 Tauri Android release 构建注入 release 签名配置
# 在 `tauri android init` 之后、`tauri android build` 之前运行。
# 参考: D:\workbench\iboard\scripts\ci\android-signing.sh
#
# 依赖 (由调用方注入环境变量, 不要写死密钥到脚本/仓库):
#   ANDROID_KEYSTORE_B64  - base64 编码的 keystore 文件内容 (CI secret)
#   ANDROID_KEY_ALIAS     - 密钥别名 (CI secret/variable)
#   ANDROID_KEY_PASSWORD  - store & key 密码 (CI secret; 本脚本两者用同一个)
#
# 作用:
#   1. 把 base64 密钥解码写到 $RUNNER_TEMP/wardrobe-release.keystore
#   2. 生成 gen/android/keystore.properties (Tauri 签名约定读取此文件)
#   3. 修改 gen/android/app/build.gradle.kts, 添加 signingConfigs.release
#      并让 buildTypes.release 使用它, 产出已签名 APK
