Pull request overview

This PR enhances the DevalueError class to include additional debugging context by adding value and root properties to error instances. This helps users diagnose serialization failures by providing direct references to both the problematic value that failed serialization and the root object being serialized.

Key changes:

• Extended DevalueError constructor to accept and store value and root parameters
• Updated all error throwing locations in uneval.js and stringify.js to pass these additional parameters
• Exported DevalueError class from the main index for external consumption
