Merge task/467 so the sweep tail can reach the three mechanisms (V-528)

attentionq.go, repair.go and internal/router/complaint.go carry the last
hand-written Russian patterns of the V-522 sweep, and they live on task/467.
internal/lexicon, internal/morph and cmd/mavend/topics.go live here. One of
the two had to move.

Four conflicts, and one of them is a real collision rather than a mechanical
one. Both branches wrote the narrative stage 0 rule. This side had
NarrativeQueryGrammars, plural, with the rest-of-day rule beside it and the
verb alternation built from the lexicon; task/467 had NarrativeQueryGrammar,
singular, which extracts the topic into Slots.Text, refuses a bare "расскажи",
and excludes the shapes that are chat ("расскажи о себе", "историю на ночь").
Resolved by keeping this side's container and this side's lexicon-built
pattern, and taking every behaviour only the other side had: the topic slot,
the empty-topic refusal, chatNarrativeTopics, and its wiring position after
TaskCaptureGrammar so "запиши" still beats "расскажи".

The rest: queryFeeds keeps task/467's conditional claim (V-474 supersedes the
unconditional one), rank.go keeps Spoken and drops pluralTasksRU because
say.CountWord is the one copy of Russian count agreement, and vendor/ was
re-vendored — the merged modules.txt claimed replaces for nexus and praxis
that neither go.mod has.

Routing fixture 58/82, unchanged from both sides.
