- Add invokeWithTimeout wrapper for TDLib API calls (2min timeout per call) - Add stuck detection to getChannelMessages: break if from_message_id doesn't advance - Add stuck detection to getTopicMessages: same protection for topic scanning - Add stuck detection to getForumTopicList: break if pagination offsets don't advance - Add max page limit (5000) to all scanning loops to prevent infinite pagination - Add mutex wait timeout (30min) to prevent indefinite blocking when holder hangs - Add cycle timeout (4h default, configurable via WORKER_CYCLE_TIMEOUT_MINUTES) - Fix end-of-page detection to use actual limit value instead of hardcoded 100 Co-authored-by: xCyanGrizzly <53275238+xCyanGrizzly@users.noreply.github.com>
