/**
 * HTTP-based streaming implementation for Microsoft Teams activities.
 *
 * Allows sending typing indicators and messages in chunks to Teams.
 * Queues incoming activities and flushes them periodically to avoid
 * rate limits.
 *
 * Flow:
 * 1. `emit()` adds activities to the queue and starts a flush if none scheduled.
 * 2. `_flush()` starts by cancelling any pending flush, then processes up to 10 queued activities under a lock.
 * 3. Informative typing updates are sent immediately.
 * 4. Message text is combined and sent as a typing activity.
 * 5. `_flush()` schedules another flush if more items remain in queue.
 * 6. `close()` waits for the queue to empty and sends the final message activity.
