Glitch/TypeError: Received Buffer when Uint8Array expected

This bug affects nodejs/test-environments

Excerpt from block.js

const bytes = codec.encode(value) // <-- Returns node:Buffer
const hash = await hasher.digest(bytes) // !!! <-- Throws if not Uint8Array

Platform agnostic proposal:

let bytes = codec.encode(value)
if (!(bytes instanceof Uint8Array) && bytes?.buffer) bytes = new Uint8Array(bytes.buffer, bytes.byteOffset, bytes.byteLength)
const hash = await hasher.digest(bytes)

I'll monkeypatch for now.
Please take it from here, thanks.

Start in src/block.js around the codec.encode and hasher.digest calls shown in the issue, then reproduce the failure in the nodejs test environment. Verify the change with the relevant existing tests or a focused reproduction, and consider the issue done when Node.js Buffer values are accepted without breaking other byte-array inputs.
