- [ ] Implement `delete` method in `Likes` class
- [ ] Update `ILikes` accordingly

- [ ] Update unit tests

**NB**: Paid X API access required

Start with the Likes class and ILikes interface, then consult the X Documentation for the Delete Like endpoint and its Query and Response types. Update the unit and integration tests to cover the new operation, and revise the README's supported endpoints, example, and table of contents. The work is complete when the implementation, tests, and documentation all include Delete Like support.
