feat(scripts): added native leaf-package publish checks to install smoke tests

- Added repeatable `--tag` argument parsing in `gen-npm-packages.ts` and threaded parsed tags into `generateNpmPackages` for targeted leaf publishing.
- Exported `prepareNativeCorePackage` and expanded package manifest typing to support scripted manifest rewrites used by release workflows.
- Reworked install-test smoke logic to pack the host leaf package, pack the rewritten natives core, and assert the platform leaf package resolves from the core optional dependency.
