📦 Add AUR package for Arch Linux installation

Introduce an Arch User Repository package for Arch Linux users:

- Create PKGBUILD with binary downloads for x86_64 and aarch64
- Add .SRCINFO metadata for AUR compatibility
- Include update-aur.sh script to automate version bumps and
  SHA256 checksum calculation from GitHub releases
- Exclude aur/ directory from crate package to reduce download size

The package uses pre-built binaries from GitHub releases, avoiding
the need for Rust compilation on end-user systems.
