fix(refactor): prefix built-in node module imports

Since v5 relies on node >= 18, this is now possible (since v16, v14.18.0
[^1][^2]).

It's functionally irrelevant:
1. It's not required for CJS nor ESM (with a few exceptions [^3])
2. It has no performance promises

However, there are upsides to this approach:
1. It brings clear boundaries to what's a built-in and what's an
external dependency
2. It reduces the risk of importing unwanted deps where a built-in is
expected
3. It's slightly more interoperable with other JS runtimes that provide
node compatibility[^4], albeit only during development. Once imported
from npm, built-ins are assumed.
