Adds commonly needed operations like takeWhile and zip, which are missing from Java 8 Stream API, enabling more expressive data processing pipelines as shown in the README examples with infinite streams and element-wise combination.

Seamlessly integrates with existing Stream API without introducing heavy dependencies, maintaining the same functional design principles for declarative code.

Provides Streamable<T> for creating reusable stream sources, similar to Iterable, which is useful for multiple iterations over the same data without re-creating streams.

Includes collectors like unique and toFutureList that handle edge cases efficiently, such as ensuring a stream has exactly one element or managing CompletableFuture streams with fail-fast error handling.
