Greptile Summary

This PR centralizes extension map discovery and adjusts setup compilation paths. The main changes are:

• Replaces direct iTopExtensionsMap construction with a shared factory.
• Tracks scanned module root directories on the extension map.
• Updates setup and data-audit compilation to use selected extensions and modules differently.
• Adds feature-removal coverage for newly added extensions during dry removal.
• Updates setup unit tests and fixtures around extension maps and compilation.

Confidence Score: 3/5

This should be fixed before merging.

• The data-audit compile path can ignore the wizard-selected source tree.
• Upgrade checks can run against the wrong datamodel roots.
• The previously reported Hub download issue still affects an extension install path.
