fix: include `files` field in package.json for npm distribution

Hotfix: Include dist folder in npm package

The previously published version 0.1.1 of the package is missing the dist folder, which was present in version 0.1.0. This issue prevents the package from functioning correctly.

This merge request adds the files field to package.json, explicitly specifying dist/**/* for inclusion in the npm package. This ensures the dist folder is properly included in future releases.
