V3 changes

[guybedford]

Looks like we may have a V3 on the horizon.

Possible API changes:

• Exports to return an object
• Full build (non-minimal) to expose non-minified field values
• Import type for star reexports

Bumping Node.js min version.

For the bump: could we make that Node.js 18+?

While it is already outdated, it would allow to support other tools that still have older support.

Node.js 18+ could work.
