Release v2.2.4
fix: add repository.url to package.json for npm provenance NPM publish failed: package.json "repository.url" was empty, expected to match "https://github.com/jiangood/open-admin" from provenance. Bump version to 2.2.4 (2.2.3 already deployed to Maven Central). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
