fix: fix release build error (#364)

Context https://neondb.slack.com/archives/C06HN3DFX7T/p1751464594765169

There is an error during the release build: `Module format "cjs" does
not support top-level await. Use the "es" or "system" output formats
rather.`.

This change was introduced in
#339

Reproduce by `rm -Rf node_modules && bun install && bun run build && cp
dist/package*.json ./ && node pkg.js`.
