Research direction

Start with the minimal C reproducer using the declaration and definition of a with restrict, then investigate how the C/C++ extension indexes or resolves the function definition. Confirm the behavior with the reported extension and VS Code versions; done means the definition is found from the declaration or its corresponding navigation action.
