interface StreamRespondOptionsOptions for StreamController.respond / framework respond().
Targets a single pending interrupt (interruptId / namespace) and
carries run-level config and metadata onto the resume so the
resumed run applies the same configurable values (model, user context,
timezone, …) and metadata (trigger source, test flags, …) a fresh
StreamSubmitOptions would. The server folds these into the run
it starts to service the input.respond command.
To resume several interrupts pending at the same checkpoint, use StreamController.respondAll instead.
The assistant config.
Target a specific pending interrupt. Omit when exactly one interrupt is pending to resume the newest unresolved one; pass it when several can be active (parallel subagents, fan-out, nested graphs) so you resume the interrupt the user acted on.
