SafeCompleter<T extends Object> class
A wrapper around Dart's Completer that prevents it from being completed more than once.
It provides an API for resolving a value and safely accessing the result via a Resolvable. This is useful for managing one-off asynchronous operations where multiple callers might attempt to set the result.
