.SYNOPSIS
    v3.1.3: Bookworm 完整卸载实��脚本

.DESCRIPTION
    由 卸载Bookworm.bat 调用. 集中所有 PS 清理逻辑, 避免 cmd 多行 PS 转义.

    清理项:
      [1] 桌面 4-5 个 .lnk (启动/更新/体检/卸载/旧 Bookworm.lnk)
      [2] ~/.claude/ 整个目录 (skills/hooks/agents/凭证)
      [3] HKCU:\Software\Bookworm (DPAPI 缓存 + Toast 备份)
      [4] PS7 + PS5.1 双 profile.ps1 的 BW_CRED + BW_CLIP 块
      [5] HKCU 截图 Toast 设置还原 (从备份)
      [6] ANTHROPIC_* + BW_LICENSE_KEY User 环境变量
      [7] 提示用户手动删 bookworm-boot 目录

    保留 (公共依赖, 不主动卸):
      - Node.js / Git / PowerShell 7 / Claude Code (npm i -g)
