  • AgentStatusUpdateDto (backend/Dtos/AgentStatusUpdateDto.cs): DTO with AgentId, DisplayName, Role, Status, CurrentTask, TaskProgress, TaskElapsed, SessionKey, Channel, LastActivity, ErrorMessage.
  • AgentStatusHubExtensions: Server-side extension methods PushStatusUpdateAsync and PushStatusUpdateToFleetAsync for background services to broadcast via IHubContext.
  • Program.cs: Registered SignalR services and mapped hub endpoint at /hubs/agent-status.
