Typescript ESM CJS references

Nextjs fails to detect ESM modules correctly when using exports in package.json

Ran into problem with tsup generating d.ts files with incorrect export section export default blah vs export = blah.

arethetypeswrong reported this as FalseExportDefault

Found a workaround in this tsup issue https://github.com/egoist/tsup/issues/572#issuecomment-1680153238 We may be able to remove "--cjsInterop --splitting" once that is addressed.

Import named default is typed differently than default import (with moduleResolution: node16))

What’s confusing about modules?
