Create dist dir before packing wheels

Ensure the target dist directory exists before invoking the wheel packing step in SimplePackageBuilder and PythonPackageBuilder. Introduced a dist_dir variable (Path.cwd() / 'dist') and call dist_dir.mkdir(parents=True, exist_ok=True), then pass dist_dir to the pack command to avoid failures when the directory is missing and reduce repeated Path.cwd() calls.
