/**
 * Assemble the plugin-registry installable root (`registry/`) from the built
 * `lib/` output. Run after `pnpm build`:
 *
 *   pnpm build
 *   node scripts/package-registry.mjs
 *   dsh registry install ./registry
 *   dsh registry enable dsh-external/dsh-better-sidebar
 *
 * The registry install copies the whole source directory (`cp -r`), so
 * installing the repo root would drag in `node_modules/` (machine-local
 * `link:` devDependency symlinks, node-pty binaries) and `.git/`. This
 * staging directory carries exactly the files the manifest references plus
 * the docs — same layout as the dsh-subagent-tree `registry/` pattern. It is
 * gitignored and rebuilt from scratch on every run.
