Stream endpoint:
- Increase read timeout to 600s for progressive audio generation
- Use larger 16KB chunks for smoother playback
- Remove misleading Accept-Ranges header (we don't support range requests)
- Add logging for stream start/completion
- Properly close httpx client after streaming
Frontend:
- Wait for 'canplay' event before attempting autoplay
- Add event listeners for play, error, stalled, waiting
- Native audio controls' play button now properly hides tap message
- Add 5s fallback timeout if canplay doesn't fire
