Description
Monade provides synchronous and Promise-based monads with operations such as `of`/`pof`, `map`, `tap`, `chain`, and `val`. It includes synchronous and asynchronous Kleisli-arrow builders (`ka`/`pka`), extensible devices (`dev`/`pdev`) with custom chainable and terminal methods, and option helpers (`opt`/`popt`) for converting failures to null values.
