+/// This class is responsible for modifying the served JavaScript files
+/// to include the injected DWDS client, enabling debugging capabilities
+/// and source mapping when running in a browser environment.
+///
+/// The `_enableDebuggingSupport` flag determines whether debugging-related
+/// functionality should be included:
+/// - When `true`, the DWDS client is injected, enabling debugging features.
+/// - When `false`, debugging support is disabled, meaning the application will
+///   run without debugging.
