How to Use DartExceptor: A Lighter Way to Handle Errors in Dart 3

DartExceptor is a lightweight, zero-dependency Dart 3 package that implements a typed result pattern to replace bare try/catch blocks. It introduces a `Trace<T, E>` sealed type with `Ok` and `Err` implementations, plus four focused methods: `split` (exit point requiring both handlers), `map` (transform success), `mapError` (transform failure), and `bind<B>` (chain operations with short-circuit on failure). The package eliminates the need to rewrite ~150 lines of boilerplate per project and slots cleanly into clean architecture layers. It is compared to `dartz`, offering a simpler API without Haskell-style conventions or transitive dependencies.
