Simplify agent services

- Remove response message creation and task status updates from run#AgentTask
- Let poll#AgentQueue handle all status management
- Pass noStatusUpdate=false to run#AgentTask to prevent auto status changes
- run#AgentTask now just calls LLM and returns result
This fixes NullPointerException issues and simplifies the agent flow
