FR: include the label in the pueue log header output

[mjpieters]

Is your feature request related to a problem?

For my post-processing queue I put the number of items to process, in the label. That's because the job output only tells me what (numbered) files are done, not how many files there are to process. I could put that in the log output at the start, but that then requires me to use pueue log --full to get that info out again when I check on a job.

To check on the job progress does require two checks though: I need to look at the pueue status output to see the label, then the pueue log output to see how far along it is.

Describe the solution you'd like

I'd like to see the pueue log header for a task to be extended to include the label. Currently the header shows:

• a boxed Task [TASK_ID]: [Status] line.
• The task command, path, and start time, and for done jobs, the stop time.

The label should be added to this.

Describe alternatives you've considered

I currently use a custom jq script to output this information; the last log lines plus the above info with the label included.
