Fix the nudge phrasing prompt: stop teaching the model to echo the example

Browse Source 
The system prompt showed the JSON contract as {"response": "..."} and the
user prompt repeated it. A 0.8B copies whatever sits in the response slot, so
7 of 15 nudges came back as literally "...".

Changes, all prompt-side — the {"response","mood"} contract is unchanged:
- nudge system prompt is Russian, feminine self-reference, with filled-in
  examples on topics that never appear as rules, so copying them is visible
- rule names get a Russian gloss and a required keyword, named last in the
  prompt where a small model weights it hardest
- durations render in Russian, not English
- the no-parse fallback says something Russian instead of "water — care",
  which was going straight to a Russian piper voice
- same "..." placeholder removed from replier_llm.go

Scored on internal/phraser/eval: 0/15 -> 13/15.
