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.

+
+            Pre-built artefacts for every supported platform — the same files that
+            were uploaded to crates.io, PyPI, and npm by this workflow run.
+
+            - `*.whl` / `wickra-*.tar.gz` — Python wheels + sdist (5 platforms, ABI3 ≥ 3.9)
+            - `wickra.*.node` — native Node bindings (linux-x64-gnu, darwin-x64,
+              darwin-arm64, win32-x64-msvc)
+            - `wickra-*.tgz` — npm-pack tarballs (main package + per-platform subpackages + WASM)
+            - `*.crate` — cargo source crates (wickra-core, wickra-data, wickra)
+
+            ### Auto-generated changelog
+
+            See below; GitHub computes it from the commits since the previous tag.
