Times every kstage and prints a mode-aware hit/miss verdict; a mode=roll miss is the ~3min/node suspect behind 10.5-vs-7 min legs. Measurement rides the next real roll.

feat(deploy-kernel): prestage hit/miss verdicts — make the silent cost loud ... 67c17c657a

The sf36 workers roll spent ~10.5 min per serialized node while the
step metrics floor says ~7 (roll-node 4.2-5.7m + green 1.3-3.2m). The
suspect gap is pre-stage misses: the prestage fan-out tolerates
failure by design (continueOn), and a missed node repays the full
image pull inside the serialized window with NOTHING recording that
it happened.

Every kstage now times  and prints
 —
in prestage mode a long stage is the machinery working; a mode=roll
miss is the regression signal. Next real roll answers the question
from evidence instead of theory.
