say: one count rule everywhere, and a page she can explain (V-521)

The PR 113 review found four defects in one line file. Swept the other four
families and the Go side for the same four.

The JSON was clean: no undeclared placeholder, no abbreviation spoken, no
single-variant entry left unfixed. One register leak — page_blocked read
"robots.txt" out loud, which is a filename, not a reason he can act on.

The count rule was not clean. Four more copies of the three-way agreement
existed and two of them were wrong: ruPlural produced «1 минут назад» and
«5 часа назад» because formatTime spelled the noun out. pluralTasksRU was a
fifth copy. All of them now call say.CountWord. The pending-notification
summary picks the whole phrase, because the adjective declines with the noun.
