fix: keep only source-map extracted node_modules, exclude pnpm artifacts

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.
