Fix GLIBC compatibility and binary naming in CI/CD

- Use ubuntu-20.04 for Linux builds to ensure compatibility with older GLIBC (like Debian 12).
- Standardized binary names to include architecture (voxvera-linux-x86_64).
- Improved install scripts to handle 404 errors and prevent empty file installation.
