Count the rides a question takes, without the reset (V-663)

MaxSuspends did not move the number it was written for. Twenty-six of 140
turns carried a parked clarify tail before it landed and twenty-six after.

Two bounds rearm each other. An aside spends no attempt, so MaxAttempts
never reaches it. A turn reading as a failed answer zeroes Suspends, so
MaxSuspends never reaches the asides. Alternating them restores each bound
with the other's traffic. Measured on 2026-08-08: one question about a
reminder's day rode turns 7 to 13.

PendingQuestion.Rides is the same event counted without the resets. Set
once, incremented only in noteSuspended, carried across the re-park in
askRemainingGap, read by nothing that could lower it. MaxRides is 4, one
looser than MaxSuspends so the tighter statement about a run stays
reachable.

It ends the measured ride one turn early and no more. Most of that ride is
attempts, spent because classifyTurnRole reads "спасибо" and "привет" as
failed answers. Said so in the constant and in the design doc rather than
claiming a fix.

+This is a bound, not a cure. It ends the measured ride one turn early. Most of

 The re-ask is also two sentences rather than one. It used to be spliced onto the
 answer with a comma. On a real answer that buries the question in the tail of
 one run-on thought:
