Bump version to 1.1.1

- Fix version-check.js to use git tag version for releases
- Add new-version.js script for proper version/tag synchronization
- Update package.json to correct version 1.1.0

The new-version.js script ensures package.json and git tags are always synchronized by:
1. Updating package.json with new version
2. Committing the change
3. Tagging the commit

This prevents version mismatches and git dirty states.
