/**
 * A subagent's report, as its orchestrator receives it. The orchestrator reads
 * the report the way it reads its own answers, so the report feeds the same
 * afterthought recall: the memories it calls to mind are offered to the
 * orchestrator's conversation and arrive on its next event.
 *
 * Claude Code hands a foreground subagent's report back as the Agent tool's
 * result; a background subagent's report arrives later as a task notification
 * in the orchestrator's prompt (official hooks docs: UserPromptSubmit fires for
 * a background subagent reporting back to the session that started it).
