Fixed
- Install failure on Linux servers: the 1.3.0 package was built with backslash path separators, which Linux/PHP hosts treat as literal filenames instead of folders. This broke extraction and caused "JSON.parse: unexpected character" and "missing manifest file" errors during install (#4). The package is now built with forward-slash separators and installs correctly.
No functional code changes from 1.3.0, packaging fix only.
