perf(audio): smooth playback time and RMS-based peak at 60Hz
Interpolates audio playback time between callbacks using CLOCK_MONOTONIC
for smooth 60Hz updates instead of coarse 8-10Hz steps.
Replaces artificial peak decay with true RMS calculation over 50ms
window. Ring buffer computes RMS directly on internal buffer without
copies for efficiency.
All backends updated with get_callback_state() interface for time
interpolation. Tests passing (34/34).
