8ball: fix substring pronoun bug, switch to 3B model

- Fix about_jared/about_wynter using substring match — "they" matched
  "he", "theme" matched "he", etc., routing Wynter's questions to the
  wrong branch. Now uses \b word boundaries via re.search.
- Switch BALL_MODEL default from sadiq-bd 1B uncensored to
  llama3.2:latest (3B) — the 1B model hallucinates, ignores persona
  instructions, and mentions Jared randomly. GPU is now working on
  Arc A380 at ~25 tok/s so the larger model is practical.
