agent-platform release v4.79.0

Added

• The Klaus Gateway board shows the whole turn as a person sees it: “Turn done (final flush), p50 and p95” (giantswarm/giantswarm#37787). The panel sits beside “Time to first text” and shows the time from the message’s arrival to the last edit of the answer in the channel, from klaus_gateway_turn_phase_seconds{phase="final_flush"}. Before, the board showed only this phase’s p95, inside “Turn phases, p95”.
