/**
 * Where and how `@vscode/windows-process-tree` is rebuilt from source.

 * node-gyp must run from the package's physical directory, never the
 * `node_modules` symlink/junction pnpm installs there: gyp expands the
 * node-addon-api dependency by probing node (whose cwd resolves to the
 * physical path), gets back a store-relative `../../../../node-addon-api@…`
 * hop, then resolves that hop against the rebuild cwd. From the link path the
 * hop escapes the store and configure fails with "node_addon_api.gyp not
 * found" (run 32999886072).
