KeyboardObserver

The README shows a direct comparison where KeyboardObserver replaces multiple lines of NotificationCenter setup with a single observe call, significantly reducing code complexity.

Uses structured types like KeyboardEvent and KeyboardEventType, making code less error-prone by avoiding manual parsing of notification dictionaries, as highlighted in the features.

Observer instances automatically stop observing when deinitialized, preventing memory leaks without the need for manual removal, which is a key advantage over raw NotificationCenter.

Provides a closure-based approach that improves readability and maintainability compared to selector-based notification methods, as demonstrated in the usage example.
