This function creates and sends a UI message that will be rendered in the UI. It also updates the graph state with the new UI message. Args: name: Name of the UI component to render. props: Properties to pass to the UI component. id: Optional unique identifier for the UI message. If not provided, a random UUID will be generated. metadata: Optional additional metadata about the UI message. message: Optional message object to associate with the UI message. state_key: Key in the graph state where the UI messages are stored. merge: Whether to merge props with existing UI message (True) or replace them (False). Returns: The created UI message.

This function combines two lists of UI messages, handling both regular UI messages and `remove-ui` messages. When a `remove-ui` message is encountered, it removes any UI message with the matching ID from the current state. Args: left: First list of UI messages or single UI message. right: Second list of UI messages or single UI message. Returns: Combined list of UI messages with removals applied.
