Fix package.json entry point to use index.ts

- Changed main field from "logger.ts" to "index.ts"
- Bumped version to 1.0.1-beta.2
- Updated IOR identifier to match new version

This fixes the LogLevel export issue where importing from the
resolved module couldn't access LogLevel because the entry point
was bypassing the proper index.ts re-exports.
