Code Review

This pull request adds important error handling for parsing the Angular build output manifest, which improves the robustness of the adapter. The implementation is straightforward and correct. I have provided a few suggestions for improvement, including correcting a type assertion, adopting a more modern error-chaining pattern, and adding a unit test to cover the new error handling path. Overall, this is a valuable change.
