Phase events should have comment

We should prepare a comment for phase events.

For shuffled it should be global and be logged at phase end for phase
For single it should be part of the annotation and at the end of the scenario

No files or tests are named. Start by locating the phase-event handling for shuffled and single execution, then trace where phase-end logging and scenario annotations are produced. Done means shuffled events have a global comment logged at phase end, while single events appear in the annotation and at scenario end.
