BroadcastToSystem

Publishes a value on the client's system broadcast channel under broadcastId, where the host application and any mounted SystemBroadcastListener tile can pick it up — the outbound half of the bridge between server-declared flows and native app code. data chooses the payload: incomingBroadcastData publishes incomingData, inlineBroadcastData publishes a literal declared on the event. Consumes incomingData as the payload when data is incomingBroadcastData. Dispatches onSuccess (no data) after the value was published; onFailure (no data), only in the incoming-data case, when incomingData is null so there is nothing to publish.
