Restore node_modules to exact state from cli.js.map extraction: - Move .ignored/ and .ignored_* files back to original package paths - Remove pnpm symlinks (replaced by real source-map directories) - Update .gitignore: only exclude /dist/, .pnpm/, .bin/, .ignored* dirs - All package dist/ folders are now preserved as part of source-map files After clone, run `pnpm install` to get pnpm-managed symlinks for building. The committed node_modules contains the original TypeScript/JS source files as bundled in cli.js.
