ci(macos): GitHub Actions universal .pkg 构建与发布

- release.yml 重构为 build-windows / build-macos / release 三 job 并行,
  macOS 产 universal(arm64+x86_64) .pkg 并入同一草稿 Release;
  release notes 生成由 PowerShell 改写为 bash(逻辑等价)
- ci.yml 加 changes 门控 + macos-check(仅 wind_macos/**、wind_input/** 改动触发)
- build.sh/app.sh/setting.sh/pkg.sh 支持 WIND_MAC_UNIVERSAL / --universal:
  Go lipo 合并、swift --arch 双架构、wails darwin/universal、hostArchitectures
- app.sh 从 VERSION 文件注入 CFBundleShortVersionString(版本随 tag 贯通)
- pkg.sh 产物改名 -macOS 后缀, 预留 Developer ID 签名 + notarytool 公证接口
- CI 工具链对齐 dev: pnpm 11.3.0 + Node 22 (pnpm 11 需 Node>=22.13;
  pnpm 9 不识别 pnpm-workspace.yaml 的 allowBuilds 键)
