v1.0.1 — Composer configuration and README update

This patch release fixes minor but important issues from the initial v1.0.0 release:

• Added missing updates to composer.json including PHP version requirement and PHP DOM extension declaration (ext-dom).
• Updated the README file with improved usage examples and clearer documentation.
• Removed the "version" field from composer.json to follow best practices for package versioning via Git tags.
• General cleanup and corrections to ensure smoother installation and usage.

Thank you for your patience, and we recommend upgrading to this patch version for the best experience.
