PR Overview: Live Task Progress Updates Across Chat FrontendsSummaryThis PR introduces a live task progress update system that provides real-time status updates to users during long-running AI tasks across Slack, Telegram, and Teams frontends. The system posts a "working on it" placeholder message and periodically updates it with AI-generated progress summaries based on execution traces, then replaces it with the final answer when complete.
