# ============================================================
# Thing 构建发布脚本（目标：自建 Gitea release）
#
# 用法：
#   .\scripts\release.ps1 -Version 0.2.0                # 同步版本号 + 构建 + 发布
#   .\scripts\release.ps1 -Version 0.2.0 -SkipBuild     # 复用现有构建产物，直接发布
#   .\scripts\release.ps1 -Version 0.2.0 -SkipPush      # 只构建+整理产物，不上传
#
# 发布产物（上传到 https://gitea.atie.fun/LFeng/Thing 的 v{Version} release）：
#   thing_{v}_x64.exe           便携免安装版（无内核）
#   thing_{v}_x64.msi           安装版 MSI（去掉 tauri 默认的 _en-US 后缀）
#   thing_{v}_x64-setup.exe     安装版 NSIS
#   thing-hk_{v}.zip            ThingHK 硬件监控内核（mihomo 继续走代理模块内置的 GitHub 下载）
#
# 前提：
#   - Gitea token 已配置为环境变量 GITEA_TOKEN（-SkipPush 时不需要）
#   - 可选 -NotesPath 指定 release notes 文件（Markdown 文本），
#     缺省时使用 scripts/release-notes.md（若存在），否则用简单占位文本
