Clean risk

Adds HTML validation results to Chrome Developer Tools for HTML5 pages.

This extension checks HTML code and syntax using an embedded HTML Tidy validator that runs locally in the browser. It shows the number of errors with a browser icon and provides detailed errors, warnings, optional accessibility warnings, and a cleanup proposal in Developer Tools.
