Fix ARM64 support and improve test robustness

- Update lib/index.js to properly support ARM64 and other architectures
- Make tests skip gracefully when native module cannot load
- Add build output verification steps to CI workflows
- Improve error messages with more diagnostic information

This allows the module to work on Apple Silicon (ARM64) Macs and
other non-x64 platforms by properly falling back to natively built binaries.
