feat(batch-agent): extract Batch Agent Service (Step 3)

- agent_runner: local directory + cloud agent orchestration via Redis
- 5 domain agents: filesystem, task, note, project, timeline
- integrations: Gmail, MS Graph (Outlook + Teams)
- journey: guided chatbot conversation to build prompt_template
- routes: REST endpoints (catalog, can-create, trigger)
- redis_consumer: subscribes to batch:request:* pattern
- ws_context: Redis-based execute_on_client for tool round-trip
- Dockerfile with 300s timeout for long-running batch jobs
