Research direction

Investigate how ng inspector retrieves scope data for both 'Controller As' and older syntax. Compare the DOM or internal data structures used by the extension. Look at the source code in the repo, particularly files related to scope inspection. There are no existing PRs or comments to reference, so focus on understanding the difference in scope binding between the two syntaxes.
