Add Arch Linux packaging, cross-compilation support, and binary generation

- Introduce Arch Linux package build process, supporting both x86_64 and aarch64 architectures.
- Add Arch-specific configuration files for service, sysusers, and tmpfiles to facilitate system integration.
- Update packaging script to dynamically handle Arch-specific builds and configure PKGBUILD fields.
- Add cross-compilation support, enabling building for ARM (aarch64) on x86_64 systems.
- Implement binary generation for both architectures, allowing separate or unified binary outputs.
- Include npm scripts to automate Arch build and cross-compilation processes.
- Simplify deployment and integration for Arch-based systems.
