Add comprehensive agent activity tracking

- Enhanced Agent struct with current_activity, current_files, and activity_history fields
- Created ActivityTracker module to infer activities from tool calls
- Integrated activity tracking into MCP server tool routing
- Updated task board APIs to include activity information
- Agents now show real-time status like 'Reading file.ex', 'Editing main.py', 'Sequential thinking', etc.
- Added activity history to track recent agent actions
- All file operations and tool calls are now tracked and displayed
