Add Node.js bindings (cuvs-node) to language support / integrations list

[skunkwerks2020]

Hi cuVS team,

We've built and open-sourced Node.js bindings for cuVS: cuvs-node.

cuvs-node provides native C++ N-API bindings to the cuVS C API, giving Node.js developers in-process GPU-accelerated vector search.

What's implemented:

• CAGRA (build, search, serialize, deserialize)
• IVF-Flat (build, search, serialize, deserialize)
• IVF-PQ (build, search, serialize, deserialize)
• Brute-force (build, search, serialize, deserialize)
• CAGRA to HNSW conversion (build on GPU, serve on CPU)

Status:

• 99 tests passing
• Verified on A10, A100 H100 GH200, B200
• Published on npm: npm install cuvs-node
• Apache-2.0 licensed
• Benchmarked at 733x faster index builds vs CPU (hnswlib-node) at 768d, 1M vectors on A100 SXM

• npm: https://www.npmjs.com/package/cuvs-node
• Blog: https://638labs.com/blog/2026-04-13-opensource-nvidia-cuvs-node-bindings/

We'd love to be listed alongside the other cuVS language bindings and integrations.

Happy to submit a PR updating the README or docs if that's preferred.

cheers
