Edge TTS websocket requests fail intermittently, and a single transient failure during preload silently dropped the cached audio chunk, which could stall playback. Add a #createAudioUrlWithRetry helper that retries createAudioUrl up to 3 attempts with a short backoff, bailing early when the abort signal fires. Both the immediate and background preload paths in speak() now use it. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
