#!/usr/bin/env bash
# 发新版的一条龙脚本。
#
# 用法：
#   ./scripts/release.sh <version> [<build_number>] [<release_notes_file>]
#
# 例：
#   ./scripts/release.sh 1.0.02 A1004 docs/release-notes/1.0.02.md
#   ./scripts/release.sh 1.0.02
#
# 流程：
#   1. 改 build-app.sh 里的 APP_VERSION / BUILD_NUMBER
#   2. 跑 build-app.sh 出 .app
#   3. ditto 打包成 OpenLess-<version>.zip
#   4. sign_update zip → 拿 EdDSA 签名 + 长度
#   5. 在 appcast.xml 里追加新 <item>
#   6. git commit appcast.xml + build-app.sh
#   7. git tag v<version> + push main + push tag
#   8. gh release create + 上传 zip
#
# 依赖：
#   - /tmp/sparkle-tools/bin/sign_update（首次会自动从 Sparkle release 下载）
#   - gh CLI 已登录
#   - Keychain 里有 Sparkle EdDSA 私钥（已生成一次性）
