📦 Add multi-architecture support for package builds

- Add ARM64 (aarch64) target alongside existing AMD64 builds
- Configure cross-compilation toolchain for ARM64 builds
- Update package asset paths to work with target-specific builds
- Remove global rustflags config in favor of per-build settings
- Upload separate artifacts for each architecture (amd64/arm64)
- Optimize man page upload to run only once per build matrix
