feat(02-02): enhance agent prompts for non-code task deliverables

- Add deliverable requirement sections for research and content tasks in prompt-builder
- Research tasks instruct agents to produce knowledge entries, documents, or substantial comments
- Content tasks instruct agents to produce documents, social media drafts, or substantial comments
- Auto-infer task_type from assignee department on task creation in api-server
- Import inferTaskType in both prompt-builder and api-server
