fix: human fight timing, creative timer, TTS reliability, add sweary/vibe narrations

- Fix invisible characters in human mode: init live scene BEFORE starting
  challenge polling so entrance plays before first question appears
- Cap creative writing timer to 10s for multiple choice (just tapping buttons)
- Fix TTS reliability: precache priority phrases (Round 1-7, Fight!, K.O.)
  all at once instead of in slow batches; prevent duplicate precache runs
- Add 10 vibe-coded narrations (~20% chance): "I was vibe coded into existence"
- Add 15 sweary narrations (~30% chance): raw unhinged fight commentary
- Add sweary draw and retro narrations
