/**
 * In-memory Teams conversation store.
 *
 * Unlike Slack, Teams does not hand the bot a free, queryable history of a
 * conversation, so the adapter keeps the transcript itself: the listener
 * records each incoming user message, and the run renderer records the agent's
 * reply. Each turn builds a fresh AG-UI thread id (the durable history is held
 * here, not server-side) and seeds the agent with the accumulated transcript.
 *
 * The transcript retains a message's multimodal content (an uploaded file's
 * decoded contents), not just its text, so a follow-up turn can still act on
 * data the user only sent once. This grows context for long file-bearing
 * conversations; a production {@link ConversationStore} can cap or summarize it.
 *
 * This is the batteries-included default. It is deliberately swappable: a
 * production deployment that needs the transcript to survive restarts can
 * implement {@link ConversationStore} against a real datastore and pass it in.
