ci: add macOS workflow and fix FUSE compatibility issues

- Add GitHub Actions CI workflow for macOS and Ubuntu.
- Resolve macOS FUSE compilation errors by disabling macFUSE extensions.
- Revert to using standard struct stat and fuse_fill_dir_t in src/fuse_local.c.
- Ensure cross-platform compatibility for file attributes and directory listing.
