feat: enhance zed integration with TodoWriteTool and TaskTool support (#992)

- Implemented detection and handling for TodoWriteTool to route updates as plan entries instead of tool call events.
- Added sub-agent tool tracking for TaskTool, allowing for event emission and cleanup.
- Updated event listeners to manage sub-agent tool calls and approval requests effectively.
