The nudge fixture only covered nudges. The shared persona block now goes into
five prompts, and the three conversational ones were unmeasured — those are the
long free-form replies where a persona break is most likely.
Adds talk_v1.json (27 Russian cases, 9 per path) and ScoreTalk, reporting
per-path as well as per-check so a chat regression can be told apart from a
knowledge one. Reuses the persona checks; the nudge-only ones (length, mood,
no questions) are left out, since a chat reply is allowed 1-3 sentences and a
follow-up question. The LLM run is opt-in on MAVEN_LLM_URL as before.
