Fix review issues from automated code review

- Rename MAX_RETRIES to MAX_ATTEMPTS (3 total) to fix
  misleading naming
- Skip retry loop on caller-initiated aborts so explicit
  cancellations terminate immediately
- Preserve original script type via data-type attribute
  instead of always forcing text/javascript
- Recreate MutationObserver when consent changes so newly
  added elements use fresh consent data
- Fix package.json exports: point main at ESM bundle and
  add proper exports map with IIFE as separate entry
