We refined the IM experience end to end:
- Send direct messages to Slack members.
- Choose whether dispatch should @ assignees in policies.
- Feishu, DingTalk, and other cards show the latest actions on an incident.
- Pick which action types sync to IM.
- Reply in Feishu threads for new action events.
- Loop notifications now create new messages so updates trigger push notifications, not only card edits.
