Prepare 4.0.0 release

Notable inclusions:

* edition 2023 support
* improved binary serialization/deserialization
* global result now only depends on globalThis

There are no material changes to our JS API. However,
serialization/deserialization and strict dependence on globalThis may
be significant in terms of supported clients and behavior.

We generally expect the new binary handling code to be more reliable
and conformant.
