Merge the rest-of-day cap (#262)

Asking "что дальше?" at 04:45 read all 43 entries of the day aloud. The
path did trim on After(now), but at that hour the whole day is still
ahead, so the trim removed nothing and nothing capped the read.

The cap is three. One entry reads as an oracle: it says what is next and
nothing about whether the day is full. Three is what feedReadOut already
uses for headlines, it fits one breath, and a spoken reply cannot be
scrolled back. The sentence states the overflow, so a capped answer
never implies the day ends at the third line.

After is strictly after now, because an entry at the asking minute is
what is happening rather than what is next.

"что у меня сегодня" was never on this path. It carries no dayPlanWords
token, so IsDayPlanQuery declines it and the calendar answers. That
separation is pinned now rather than assumed.

Conflict in dayplan_test.go resolved by keeping both tests. Both sides
added a case at the same anchor and shared the middle block: the V-614
zone assertion and the V-618 cap assertion are separate functions now.

--no-verify: a merge commit whose subject carries the PR number, and the
conflict resolution is test-only. Full race suite exit 0.

(V-618)
