feat: add task management CLI and improve activity curation

- Add task store with dependency tracking and CLI (packages/server/src/tasks/)
- Extract principal param logic to shared util for server/app reuse
- Improve activity curator: collapse timeline, dedupe tool calls, simpler output
- Add MessageInput ref for focus control after agent cancel
- Include recent activity in wait timeout messages
