[Feature Suggestion]: Renaming a file should rename the containing class; renaming a folder should rename the namespace in all affected files

Describe the feature you'd like

This is concerning the solution explorer view.

In Visual Studio, renaming any *.cs file can prompt the user, asking whether the contained class should also be renamed (as long as the names matched). The same thing happens with folders, which will prompt the user, asking whether the namespace should be renamed as well (given the namespaces matched the folder structure thus far). All files referencing this namespace will then be adjusted, including using directives in files not related to this hierarchy at all.

This feature would be nice to have in Visual Studio Code as well. Ideally, the prompts should go both ways: renaming a class or namespace should prompt the user, asking whether the file or folder should be renamed too.

Environment Information

• OS version: Windows_NT x64 10.0.22621
• VS Code version: Code 1.79.0 (b380da4ef1ee00e224a15c1d4d9793e27c2b6302, 2023-06-07T14:26:35.552Z)
• Extension version: 0.1.83

Start with the solution explorer view and review how file and folder renames are currently handled in the C# Dev Kit. Define the prompt behavior for matching class and namespace names, including reverse renames and references in unrelated files. Done means the requested rename prompts and affected references work consistently.
