Improve JitPack build monitoring in release workflow

- Remove unnecessary 30-second wait for tag propagation
- Add intelligent polling of JitPack build status API
- Poll every 30 seconds for up to 10 minutes maximum
- Provide real-time feedback on build progress
- Exit with success/failure based on actual build results
- Include helpful links to artifacts and build logs
