feat: ship pre-generated TTS audio files for instant playback

Browse Source 
71 static voice files (9.6MB) for round calls, intros, hype lines,
and challenge announces. These play instantly from file instead of
running Kokoro TTS generation in the browser. Dynamic content
(questions, answers, narrations) still uses Kokoro.

Includes Node.js generation script (scripts/generate-voice-files.mjs)
and modified tts.ts to check static file cache before worker generation.
Static audio works even before Kokoro model finishes loading.
