ci(release): show meaningful release notes on publish

The GitHub Release body only said "See CHANGELOG.md for details", forcing
readers to open the changelog to learn what shipped.

- Add a "Prepare release notes" step that extracts the newest CHANGELOG
  section (grouped Features/Bug Fixes) into RELEASE_NOTES.md alongside the
  install command.
- Replace the deprecated actions/create-release@v1 with
  softprops/action-gh-release@v2.
- Enable generate_release_notes so GitHub appends "What's Changed" (with PR
  links), "New Contributors", and the full changelog comparison below the
  summary.
