/**
 * Regression test for #2376: @$HOME not correctly mapped in OpenCode on Windows.
 *
 * On Windows, $HOME is not expanded by PowerShell/cmd.exe, so OpenCode cannot
 * resolve @$HOME/... file references in installed command files.
 *
 * Fix: install.js must use the absolute path (not $HOME-relative) when installing
 * for OpenCode. (Generalized to all platforms in #2831 — OpenCode `@file`
 * references are not shell-expanded on any platform.)
