Refs #19173

• Rule Reference

• TypeScript allows method overloads, where multiple method signatures can be declared but only one implementation exists.

  class A {
    foo(value: string): void;
    foo(value: number): void;
    foo(value: string | number) {} // ✅ This is the actual implementation.
  }

Is there anything you'd like reviewers to focus on?
