Let her ask three times, and let a restated answer win

MaxAttempts was 1, justified as "not a nag". Wrong reading: "not a nag" is about
interrupting unprompted, and a clarifying question is part of a conversation he
started. Now three, configurable via voice.clarify_max_attempts (default 3).
Three, because after that the likely problem is she misheard the whole request,
not one slot.

Answer used to keep the parked value, so "в три" then "нет, в пять" threw the
five away. Now a value the answer carries wins for the slot she asked about.
Only for the clarify answer — a correction in a fresh turn is followUpMerge.

The eight-field chained assertion in the Answer test is one DeepEqual now, so a
new field in Slots is covered without touching the test.
