test(windows): exercise installer lifecycle

[liugddx]

Summary

• install the final NSIS artifact silently into an isolated Windows directory
• verify the installed application from that directory, including resources, version, ConPTY, and renderer startup
• run the shipped uninstaller and require the install directory to disappear
• exercise the same lifecycle in pull-request packaging checks and the release workflow

Validation

• node --test scripts/windows-x64-release.test.mjs scripts/electron-builder-config.test.mjs scripts/ci-test-plan.test.mjs (19 pass)
• npm run test:scripts (128 pass)
• Biome, workflow YAML parsing, and git diff --check

Scope

This closes clean install/start/uninstall evidence. Version-to-version upgrade, failed-upgrade rollback, Authenticode, and automatic updates remain separate Phase 3 work in #2142.

中文说明

内容

• 将最终 NSIS 安装器静默安装到隔离的 Windows 目录；
• 从真实安装目录校验应用资源、版本、ConPTY 和桌面渲染器启动；
• 运行随安装包提供的卸载器，并要求安装目录最终消失；
• PR 打包检查和正式发布工作流复用同一套生命周期验证。

验证

• 相关单测 19 项通过；
• 完整脚本测试 128 项通过；
• Biome、workflow YAML 和 diff 检查通过。

边界

本 PR 完成干净安装、启动和卸载证据。跨版本升级、升级失败回滚、Authenticode 和自动更新仍作为 #2142 Phase 3 的后续独立工作。

Part of #2142.

Adversarial review found a real lifecycle gap, confirmed by Windows run 31401966245: installation and installed-app verification passed, but uninstall began while the detached Runtime Host was still inside its 30-second idle grace, so the install directory remained.

Updated the PR to:

• wait for every process whose executable lives under the install directory to exit before invoking NSIS uninstall;
• keep install-directory disappearance as the success condition (no cleanup retry can turn a failed uninstall green);
• preserve the primary install/verification/uninstall error when best-effort test cleanup also fails;
• use bounded retry only for the isolated test root cleanup;
• slim the orchestration mock and add focused process-order and error-preservation tests.

Local validation: 13 focused release tests pass; full fast script suite reports 160 pass / 1 Windows-only skip. A fresh real Windows package run is pending.

中文说明

对抗审查通过真实 Windows run 31401966245 发现：安装和已安装应用验证都成功，但 Runtime Host 仍处于 30 秒 idle grace 时就开始卸载，导致安装目录残留。

本次修复会在卸载前明确等待安装目录下所有进程退出；仍以安装目录由卸载器真实移除为成功标准；测试环境清理不会把失败伪装成成功，也不会覆盖原始错误。同时瘦身 mock，并补充进程顺序与错误保真测试。新的 Windows 实跑正在等待。

Windows lifecycle evidence is now green on run 31404195691.

• final NSIS install completed;
• the installed app passed resource, version, ConPTY, and renderer verification;
• the verifier observed installed processes exit after 31.6s instead of racing the Runtime Host idle grace;
• NSIS uninstall then completed and removed the install directory in 3.1s;
• the full package job passed in 9m38s, and all PR checks are green.

中文结果

修复版 Windows 实跑已通过：最终 NSIS 安装成功，已安装应用通过资源、版本、ConPTY 和渲染器验证；验证器等待安装目录相关进程在 31.6 秒后退出，避免与 Runtime Host idle grace 竞争；随后 NSIS 在 3.1 秒内完成卸载并移除安装目录。完整 package job 用时 9分38秒，PR 全部检查绿色。
