Problem

In Node.js runtimes, Buffer is an instance of Uint8Array (ArrayBuffer.isView(buf) is true), which matches isTypedArray.
When serialized, v.constructor.name evaluates to 'Buffer', resulting in the metadata annotation ['typed-array', 'Buffer'].

However, during deserialization in typedArrayRule.untransform:

const ctor = constructorToName[a[1]];
if (!ctor) {
  throw new Error('Trying to deserialize unknown typed array');
}

constructorToName['Buffer'] is undefined, causing deserialization to throw:
Error: Trying to deserialize unknown typed array

Solution

Support 'Buffer' in typedArrayRule.untransform:

• If typeof Buffer !== 'undefined', deserialize via Buffer.from(values).
• Otherwise (such as in browser environments), safely deserialize as new Uint8Array(values).

Verification

• Added unit test in src/index.test.ts verifying serialization and deserialization of a Node.js Buffer.
• All 87 unit tests pass (npm test).
• TypeScript build succeeds cleanly (npm run build).
