Access logs from active kernels

Allow users to view logs from a running kernel in real time. Right now, we can only see the kernel's output after it finishes, which makes it harder to monitor what's happening during the run.

Use Case: Being able to see active kernel logs in the terminal (or any workflow) would help users check the status of their runs as they happen. This would make it easier to catch errors early, stop the run if needed, and save time and resources especially on longer runs.
