build: add auditwheel repair to convert wheels to manylinux format

- Run auditwheel repair after building wheel to convert linux_x86_64
  to manylinux format, matching the CI/CD workflow output
- Remove original linux wheel after successful manylinux conversion

This ensures local builds match GitHub Actions wheel output.

Note: This work was completed with AI assistance (Claude Code).
