- Add scripts/lower-thinking-tone.mjs to scale the thinking-tone PCM
amplitude in-place; apply it at 0.1 so the cue is a soft indicator
instead of triggering the VAD via mic feedback.
- Drop the "Received first voice_audio_chunk" log that re-fires every
summary window because the chunk counter is reset.
- Match Spoke message icon and label sizing to the standard tool-call
badge.
- Append a spoken-input instruction so voice replies route through the
speak tool.
