feat: Add ARM64 (aarch64) support to AUR package

- Update PKGBUILD to support both x86_64 and aarch64 architectures
- Use architecture-specific sources and checksums
- Update AUR workflow to download and checksum both tarballs
- Add smart wait logic for both release assets (max 10 minutes)
- Homologize workflow naming for consistency
- Package function now detects architecture and uses correct tarball

AUR users on ARM64 devices (Raspberry Pi, etc.) can now install qbz-bin.
