StreamSourceSequenceNode.releasePreloaded() method
Tell the engine which pin to release on the NEXT source boundary, overriding the autopilot’s default "next-pin-from-sequence" pick for that single transition. Mirrors SSH’s releasePreloaded semantics: the client is responsible for any upstream pause/play around the release, and chooses when each held pin should advance onto the output. Pair with onPreloaded and an upstream pause() to backpressure long-lived held sources.
Signature:
releasePreloaded(pin: Pins): void;
