Complete usage guide for the Catcher library for error handling with the Result pattern (Ok/Err) in TypeScript. Use this skill ALWAYS whenever the user mentions catchError, catchErrorSync, catchErrorAll, Result, ok(), err(), combine, fromNullable, fromThrowable, fromPromise, or asks to handle errors without try/catch in TypeScript. Also trigger when the user wants to convert Promises to Result, chain operations that can fail, combine multiple results, or use the Railway-Oriented Programming (ROP) pattern in the project.
