router: stage 0 claims "что дальше?" and "расскажи про X" (V-498)

Both shapes carry no question mark and no interrogative, so the model saw
them with nothing deterministic in front and routed both to fact. The fact
gate caught the write and re-ran the turn as a query, so nothing broke —
what they cost was a full model round trip for a decision two patterns can
make offline.

NarrativeQueryGrammars, wired after the agenda rules so that "расскажи,
что у меня сегодня" stays an agenda question. Two exclusions, both learned
from the fixture: a capture verb in the rest of the utterance means he
asked for a note, and an entertainment noun means chat — "расскажи анекдот
про программистов" is ru-chat-003, and my first pattern took it.

The fixture had no case for either shape, which is why they went unnoticed.
Added as ru-query-020 and ru-query-021: classifier+onnx 53/77 → 55/79
(68.8% → 69.6%), both new cases answered at stage 0, false clarifies
unchanged at 0.
