Control Node.js Heap Size with ENV in Kubernetes – New --max-heap-size in 25.9.0

Node.js 25.9.0 adds support for the --max‑heap‑size flag in the NODE_OPTIONS whitelist, allowing containers on Kubernetes to set heap limits via environment variables, reducing OOM kills, while also introducing experimental stream/iter API, test‑module mock changes, new Web Crypto algorithms, and other enhancements.
