# GitHub Actions：打 tag 时构建 release 产物并发布到 GitHub Release。
#
# 产物即 OTA 更新源，命名约定（与客户端 update 模块一致）：
#   mqttx-v<ver>-<triple>-mqttx[.exe]          裸二进制
#   mqttx-v<ver>-<triple>-mqttx[.exe].sha256   侧车校验文件
#   mqttx-v<ver>-<triple>-mqttx[.exe].7z       压缩包（单条目，内部文件名 = 裸二进制名）
#   mqttx-v<ver>-<triple>-mqttx[.exe].7z.sha256
# 7z 是 OTA 主通道；裸二进制供不识别 7z 的旧客户端（≤v1.0.3）升级。
