📝 Walkthrough

Walkthrough

This pull request adds two new test cases to the detectModuleFormat test suite within the package-analysis utility. The tests verify that the module format detection logic correctly identifies 'dual' format when both main and exports fields reference JSON files, and identifies 'esm' format when only the exports field references a JSON file. The changes consist of 21 new lines of test code with no deletions.
