Added comprehensive debug logging to identify why audio playback ends without starting:
- TTS text processing and buffer management
- Audio chunk generation and transfer between buffers
- TTS task queue management
- Streaming text processing
This will help identify if the issue is:
1. Empty text being sent to TTS
2. TTS generation failing
3. Audio data not being transferred between buffers
4. Premature completion detection

The issue was that audio chunks were getting stuck in the preload_buffer
because the system required 3 chunks before starting playback. When TTS
generated fewer than 3 chunks, they would never be transferred to the
playback buffer, causing playback to end without ever starting.
This fix reduces the preload_size requirement from 3 to 1, allowing
even a single audio chunk to start playing.
