Contributions summary:Biel primarily focused on extending the Idris language's standard library by implementing and integrating monad transformers. They added type classes and instances for `MonadWriter`, `MonadState`, and `MonadReader`, along with the `MonadTrans` typeclass, to enhance functional programming capabilities. Additionally, the user refactored parts of the code base by changing `<$>` to `<*>`. These changes demonstrate a deep understanding of functional programming concepts and type system design.
