feat: Update asset metadata and enhance Agent class in SDK

- Updated modification times for various asset files in bindata.go to reflect recent changes.
- Enhanced the Agent class in libsui/agent.ts with improved type definitions and event handling.
- Introduced new interfaces for message structures and event handlers, streamlining message processing.
- Refactored the Call method to better manage message states and improve error handling.
