This change adds a Windows desktop client that embeds the web UI with WebView2. Build and installation scripts package the client and configure its URL. The desktop client can start or reuse the local backend, and the README documents installation and use.
Changes: Windows Desktop Client
Layer / File(s)
Summary
Build the desktop executable scripts/windows-desktop/build.ps1, scripts/windows-desktop/.gitignore
The build script restores and stages the pinned WebView2 SDK, generates a multi-size icon, and compiles the x64 executable. The ignore rules cover build outputs and local configuration and verification files.
Install and configure the client scripts/windows-desktop/install.ps1, scripts/windows-desktop/README.md, README.md, docs/superpowers/plans/2026-11-09-windows-desktop.md
The installer validates options, copies application files, writes desktop-config.json, and can create a desktop shortcut. The documentation describes requirements, installation, startup modes, configuration, and diagnostics. The plan records implementation and upstream-submission checklists.
Launch and host the web UI scripts/windows-desktop/RealAgenticDesktop.cs
The desktop entry point validates configuration and prevents multiple instances. The main window starts the backend, hosts the configured URL in WebView2, routes external HTTP(S) navigation to the system browser, and supports verification output.
Start or reuse the local backend scripts/windows-desktop/start.ps1
The startup script checks local service health, uses a mutex to coordinate startup, and launches the stack or legacy server path. It waits for health and logs process output.

Merge Risk: Low · up to c4fc0
The Windows desktop launcher is new and opt-in. If the worker fails during startup, the script may show a confusing error from the cleanup step instead of the actual cause. This is a small fix and does not block merge.

Explanation
The title "feat: 添加 Windows 独立桌面窗口和快捷方式安装脚本" (adds a Windows standalone desktop window and shortcut install script) matches the main change. The changeset adds a WinForms/WebView2 desktop client, plus build, install, and start PowerShell scripts that create a desktop shortcut. The title is short, specific, and follows the conventional-commit style. It does not cover every detail, such as the verification mode or the connect-only option, which is acceptable.

Verify the downloaded NuGet package before extracting it.
The script downloads the SDK package and expands it with no integrity check. The pinned version does not prove the archive content. The script then copies the extracted DLLs into the executable's install directory, where they load into a process that runs with user privileges. Compare the SHA-512 hash of the file with a value stored in the repository, and stop on a mismatch. Take the expected hash from the official nuget.org package metadata for $sdkVersion.

Handle taskkill.exe failure explicitly.
In Windows PowerShell 5.1, 2>&1 on a native command makes each stderr line an error record. The script runs with $ErrorActionPreference = 'Stop', so any stderr output from taskkill.exe becomes a terminating NativeCommandError. This can happen if the server already exited. The error then replaces the intended Worker exited message on Line 70. The script also never checks $LASTEXITCODE. Cleanup is best effort, so ignore its result and keep the original error.

Based on learnings: flag external command invocations in PowerShell scripts where $ErrorActionPreference is Stop and a nonzero exit is not checked or handled reliably.

Windows 用户目前需要手动启动 RCS 并在浏览器中打开 Web UI。本 PR 添加可从源码安装的 WinForms/WebView2 桌面窗口：使用独立 AppUserModelID 和透明图标，自动生成桌面快捷方式，双击启动或复用本地服务。
scripts/windows-desktop/install.ps1根据检出目录生成本地配置，支持指定 Bun、安装目录，以及连接已有服务。build.ps1从 NuGet 恢复固定版本的 WebView2 SDK，使用系统 .NET Framework 编译器构建，并生成多尺寸 ICO、携带 SDK 许可证声明。start.ps1启动主线 RCS + remote-control bridge；有本地 stack 启动器的检出也可使用。自动启动仅监听 127.0.0.1:3000，transport key 在本地生成。验证：
bun run typecheck通过。lint .：3321 files，无修改（本机 wrapper 缺少可选二进制，因此使用已有同版本二进制）。RealAgentic.Desktop应用标识；第二次启动退出且只保留一个窗口。限制：本次实际窗口测试连接的是已运行服务，尚未端到端验证主线上从零启动 bridge。HTTP health 只表示后端可访问，不保证 worker 或模型供应商就绪。用户须预先安装 WebView2 Evergreen Runtime，并通过正常 CLI 确认工作区信任。
