REF #211

[Copilot]

Pull request overview

This PR aims to make the job logging implementation concurrency-safe (while keeping the public interface unchanged), addressing crashes seen during job execution/restarts (ref: issue #211).

Changes:

• Switched websocket connection handling to atomic.Pointer to avoid races when closing/reconnecting.
• Refactored WebsocketLiveloggerWithFallback to use atomic swapping of the active logger.
• Refactored BufferedLiveLogger to initialize/teardown its internal channels via an atomic state pointer.
