Contributions summary:Paweł primarily contributed to refactoring the Pusher client code and integrating the client into other components. They refactored the client class, delegating methods to a default client instance, and updated various parts of the codebase, such as the `Channel` and `Request` classes, to use the client for logging and other operations. These changes also involved updating the `Webhook` class to allow for the client to be passed. The user updated the tests to accommodate the new client structure and ensure data was stored and used correctly, and they modified the client configuration, including the use of environment variables for URLs.
