Add x86_64 support to deployment script

- Add architecture detection for both ARM64 and x86_64
- Dynamically download correct Go binary based on architecture
- Add debug output to show detected architecture
- Handle 32-bit ARM with clear error message
- Update script header to indicate multi-architecture support
