Migrate Static to Wrapper

Perform mechanical, codemod-style replacement of static dependency call sites with calls to injected wrapper interfaces or built-in abstractions. Operates on a bounded scope (single file, project, or namespace) so migrations can be done incrementally.

When to Use

• After wrappers have been generated (via generate-testability-wrappers) or built-in abstractions identified
• Migrating DateTime.UtcNow → TimeProvider.GetUtcNow() across a project
• Migrating File.* → IFileSystem.File.* across a namespace
• Adding constructor injection for the new abstraction to affected classes
• Making a static utility class testable by adding an ambient seam (Step 3) while its existing call sites keep compiling unchanged
• Incremental migration: one project or namespace at a time
