.SYNOPSIS
    v3.1.1: 启动器 .lnk 端到端行为测试

.DESCRIPTION
    模拟双击桌面 .lnk → pwsh → bw-launch.ps1 → claude.ps1 链路.
    检测点:
      1. PS 进程能拉起 (无 ExecutionPolicy 拒绝 / 无 wt 切 tab 错)
      2. bw-launch.ps1 PATH 三层重载执行无错
      3. claude.ps1 解析能找到 (不一定真启动 Claude TUI, 用 --version 探测)
      4. 整体退出码 = 0 (任何运行时错就拒绝)

    替代手动双击, 集成到 build.ps1 后自动跑, 提前抓 v3.0.10 -or 类 bug.

.NOTES
    用法: pwsh -NoProfile -File tools/test-launcher-e2e.ps1
    退出码: 0=PASS / 1=FAIL
