Add Node.js SDKs

Integrate Temps platform features in Node.js / TypeScript apps.

Verified against the real published packages. A prior version of this skill referenced @temps-sdk/node (which does not exist), new Temps({ apiKey, projectId }), temps.track(), new KV({ apiKey, namespace }), kv.has(), blob.get(), blob.getSignedUrl(), TempsError — none of those exist. Confirm any API before changing it:

npm pack @temps-sdk/node-sdk@latest @temps-sdk/kv@latest @temps-sdk/blob@latest
for t in temps-sdk-*-*.tgz; do tar -xzf "$t"; echo "== $t =="; cat package/dist/index.d.ts | head -60; rm -rf package; done

The three real packages

There is no @temps-sdk/node. The platform client package is @temps-sdk/node-sdk.
