DefaultUIPayloadCompositeStrategy class

Default composition strategy that flattens and merges payloads.

Rules:

• If one payload is null, returns the other
• If both are null, returns null
• If either is UIPayloads, unwraps and merges the lists
• Otherwise, wraps both in UIPayloads

Example:

const strategy = DefaultUIPayloadCompositeStrategy();

strategy.compose(null, Failure(...)); // Returns: Failure(...)
strategy.compose(Failure(...), Warning(...)); // Returns: UIPayloads([Failure, Warning])
