claude 42d7a39c49 morning, tasks, memory: say the summaries from the file (V-506)
The three callers now read their sentences out of summary_ru_v1.json: the
plan lines in morning.Plan.FormatRU, the list and reason words in
tasks.FormatRU, and the habit readouts in memory.Profile.

Two behaviour_test assertions moved from substring to say.IsS, because the
habit gaps have variants now and a substring pins one of them. The
"по {day} у тебя обычно" variant was dropped on sight: the activities are
verbs, so it read "у тебя обычно тренируешься".

The persona scorer covers the family, and a new test asserts every gap
variant still says she has not seen enough rather than that he has nothing.
