Release 0.1.4: add GitHub Release asset attachments

Pure tooling release on top of 0.1.3. The library code is unchanged;
only the release workflow grew a new github-release job that attaches
every built artefact to the GitHub Release page so users have direct
download links next to the source archives:

- Python wheels (5 platforms) + sdist
- Native Node bindings (linux-x64-gnu, darwin-x64, darwin-arm64, win32-x64-msvc)
- npm-pack tarballs for the main wickra package, every per-platform
  subpackage, and wickra-wasm
- Cargo .crate files for wickra-core, wickra-data, wickra

The job runs at the end of the release pipeline and also accepts
workflow_dispatch so future asset-only fixups don't require a version
bump.
