Re-organize types for maximum compatibility

Add shims for TypeScript's 'node' module resolution algorithm. The exports map is only used with the `node16` algorithm.

Write types in CommonJS, so they can be exported from ESM files. The other way around is prone to, at the very least, confusing warnings.
