#!/bin/bash

#
# release.sh
# ScreenPresenter 一键发布脚本
#
# 用法:
#   ./release.sh <version>
#   例如: ./release.sh 1.0.0
#
# 功能:
#   1. 构建 Release 版本
#   2. 创建 ZIP 包
#   3. Sparkle Ed25519 签名
#   4. 更新本地 appcast.xml
#   5. 上传到 GitHub Releases
#   6. 回填 appcast.xml 下载链接为 Release 公网地址
#
# 前置要求:
#   1. brew install --cask sparkle
#   2. brew install gh (GitHub CLI)
#   3. gh auth login (登录 GitHub)
#   4. 已运行 generate_keys 生成签名密钥
