v0.1.9

Changed

• Release artifact filenames now follow the format ${project_name}-${version}-${target_os}-${arch}.${extension} (e.g., demo-flutter-rust-cpu-0.1.9-linux-x86_64.tar.gz).
• The ${arch} part is normalized to x86_64 or aarch64 depending on the build environment.
• This change applies to all platforms: Linux, Windows, and macOS.
