feat(metrics): show turn number in metrics bubble (turn N · ...)

The turn number comes from the entry's position in the metrics array
(1-based), which is correct regardless of trimming since stepId matching
aligns segments to the right entry. Now displays 'turn 3 · 12k tok' instead
of just 'turn · 12k tok'.
