chore: include LICENSE in the published npm package

[rawadtraboulsi]

Summary

LICENSE is on main (#34) but the published @better-auth/utils@0.5.0 tarball does not include it. package.json lists "files": ["dist"], so the packed package is only dist, package.json, and README.md.

This adds LICENSE to files so the next publish ships the MIT license file with the package.

A patch release after this would put the file on npm.

Test plan

• npm pack --dry-run lists LICENSE

Greptile Summary

This PR updates the npm package allowlist so the existing MIT license is explicitly included in future published tarballs.

• Adds LICENSE alongside dist in the package.json files array.

Confidence Score: 5/5

The PR appears safe to merge.

The manifest-only change explicitly includes the existing LICENSE file in npm package contents without altering runtime code, dependencies, exports, or build behavior.
