Implement Generic WebSocket Service for Real-time Communication

[rjarman]

Prerequisites

• I have searched for similar feature requests in the issue tracker.
• I have reviewed the documentation for relevant information.

Feature Description

I would like Canvas to implement a generic WebSocket service that can be used across different services, starting with the flow engine controller. Currently, the flow engine uses REST endpoints (like execute_crewai_flow_chain), but we need a more dynamic, real-time communication channel that can be reused by other services in the future.

Use Case

This feature would be useful when:

• Needing real-time updates on flow execution status
• Implementing interactive agent responses
• Building collaborative features where multiple users need to see updates simultaneously
• Creating dynamic dashboards that show real-time progress
• Implementing long-running operations that need to provide progress updates
• Future services that require bi-directional communication

Self-service

• I'd be willing to implement this feature myself.
