refactor!: remove uncrypto dependency

[pi0]

Since Node.js 18 is EOL and all supported runtime versions support global Crypto, we can drop the uncrypto dependency.

If for any reason Node.js 18 support is still needed, a light global polyfill can be used. (that's why we don't enforce node version via engines field to allow such polyfill)

import nodeCrypto from "node:crypto";

// globalThis.crypto support for Node.js 18
if (!globalThis.crypto) {
  globalThis.crypto = nodeCrypto as unknown as Crypto;
}
