feat: Wave 7 — 'where did I leave off' + Stark trivia

leftoff/recap.lua:
- Voice "на чём я остановился" / "where did I leave off" stitches a
  one-paragraph recap from four independent sources:
    1. last assistant LLM reply (jarvis.llm_last_reply)
    2. 3 most-recent memory facts (sorted by last_used_at)
    3. count + name of the next scheduled task
    4. active profile (implicit, in tone)
- Fully offline — no LLM call, just pulls from local state.

trivia/trivia.lua:
- 15 RU + 15 EN one-liners about the Stark universe (suits, arc reactor,
  in-universe trivia about J.A.R.V.I.S. itself). Doesn't overlap with
  the verbatim quote pool in personality/tony_quote.lua.

Pack count: 95 → 97. Tests: 140 still pass.
