seahaven-openswe[bot] d84c14d031 Harden schedule bump against Slack retries ... The message listener runs synchronously before the 200 ack, so a slow delete+repost can blow Slack's 3s window and be retried with no guard. Ignore retried deliveries (X-Slack-Retry-Num), stamp last_bump_ts before the delete/repost so a mid-bump retry is debounced, and skip thread replies that don't move the main timeline.
