Add GitHub Actions workflow for multi-platform builds

[Copilot]

Adds automated CI/CD pipeline to build Android (APK/AAB), Windows (MSIX), and macOS (Catalyst) packages.

Workflow Configuration

• Triggers: Push to master/main, tags matching v*, PRs, manual dispatch
• Permissions: Explicit contents: read for GITHUB_TOKEN security

Build Jobs

Android (ubuntu-latest)

• Builds both APK and AAB formats for net10.0-android
• Artifacts: android-apk, android-aab

Windows (windows-latest)

• Publishes MSIX for net10.0-windows10.0.19041.0 targeting win10-x64
• Artifacts: windows-msix

macOS (macos-latest)

• Builds and packages Catalyst app for net10.0-maccatalyst
• Artifacts: macos-app

All jobs use .NET 10.0.x SDK with MAUI workload installed. Build artifacts are uploaded and accessible from the Actions tab.

jobs:
  build-android:
    runs-on: ubuntu-latest
    steps:
      - name: Build Android APK
        run: dotnet build zuoleme.csproj -c Release -f net10.0-android /p:AndroidPackageFormat=apk

目标

为 zuoleme 项目添加 GitHub Actions 自动打包工作流，支持 Android、Windows 和 macOS 三个平台的自动构建。

具体要求

创建文件 .github/workflows/build.yml，包含以下内容：

1. 工作流触发条件

• 推送到 master 或 main 分支时触发
• 创建以 v 开头的标签时触发（如 v1.0.0）
• 创建 Pull Request 时触发
• 支持手动触发（workflow_dispatch）

2. Android 构建任务 (build-android)

• 运行环境：ubuntu-latest
• 步骤：
  1. Checkout 代码
  2. 设置 .NET 10.0.x SDK
  3. 安装 MAUI workload
  4. 恢复依赖项
  5. 构建 Android APK (Release 配置，net10.0-android 框架)
  6. 构建 Android AAB (使用 dotnet publish，Release 配置)
  7. 上传 APK 产物到 android-apk
  8. 上传 AAB 产物到 android-aab

3. Windows 构建任务 (build-windows)

• 运行环境：windows-latest
• 步骤：
  1. Checkout 代码
  2. 设置 .NET 10.0.x SDK
  3. 安装 MAUI workload
  4. 恢复依赖项
  5. 发布 Windows MSIX (Release 配置，net10.0-windows10.0.19041.0 框架，win10-x64 运行时)
  6. 上传 MSIX 产物到 windows-msix

4. macOS 构建任务 (build-macos)

• 运行环境：macos-latest
• 步骤：
  1. Checkout 代码
  2. 设置 .NET 10.0.x SDK
  3. 安装 MAUI workload
  4. 恢复依赖项
  5. 构建 macOS Catalyst (Release 配置，net10.0-maccatalyst 框架)
  6. 发布 macOS Catalyst (使用 CreatePackage=true)
  7. 上传 macOS 应用产物到 macos-app

• 当前使用调试签名，如需发布到应用商店需要配置正式签名
• 所有构建产物会作为 artifacts 上传，可在 Actions 页面下载
