/**
* link-workspace-packages.cjs
*
* Creates node_modules/@singularity-forge/* symlinks pointing to shipped
* packages/* directories.
*
* During development, npm workspaces creates these automatically. But in the
* published tarball, workspace packages are shipped under packages/ (via the
* "files" field) and the @singularity-forge/* imports in compiled code need node_modules/@singularity-forge/*
* to resolve. This script bridges the gap.
*
* Runs as part of postinstall (before any ESM code that imports @singularity-forge/*).
*
* On Windows without Developer Mode or administrator rights, creating symlinks
* (even NTFS junctions) can fail with EPERM. In that case we fall back to
* cpSync (directory copy) which works universally.
