Node 18 reached end-of-life in April 2025 and lacks globalThis.crypto, forcing unnecessary runtime fallbacks. All production runtimes (browsers, React Native, Node 20+ LTS) already provide this API, and eciesjs 0.4.16 has already dropped Node 18 support.

Node 18 support was dropped in WAPI-1133 (#76). globalThis.crypto is always available in Node 20+, so the runtime fallback to require("node:crypto").randomFillSync and the test polyfill are no longer needed.

Low Risk
Low risk: this is a tooling/runtime support change (Node 18 -> 20) with no functional code changes, but it may break local dev/consumer installs still pinned to Node 18.
