Run one agent and stream its chunks, from SUBAGENT_STARTED to SUBAGENT_FINISHED or SUBAGENT_ERROR. The package root exports this as runAgentStream. The caller checks ctx.input against agent.inputSchema first. Pass createSubagentSink() to keep the child's interrupt objects and token usage. The finished event carries interruptIds only.
