* support group sub-task
* fix optimisticCreateTmpMessage issue
* ✨ feat: add createClientGroupAgentTaskThread router for group chat
Add dedicated router for Group Chat sub-agent task execution that:
- Uses subAgentId instead of agentId for worker agent identification
- Does not filter thread messages by agentId (allows messages from different agents)
- Queries main messages by groupId + topicId only (not agentId)
This fixes the issue where thread messages query was filtering out parent
messages from other agents (e.g., supervisor) in Group Chat scenarios.
