soft sync audio via PlaybackParameters speed (rate-based, no seekTo jump)
Master = glasses (5s PlaybackPosition), slave = phone audio.
Replace aggressive seekTo-drift-corrector with smooth tempo correction:
- |diff|<=150ms (TRIGGER_BAND) -> speed 1f (hysteresis, no flutter)
- audio lags -> speed 1.02 (catch up)
- audio ahead -> speed 0.98 (slow down)
- |diff|>2000ms -> rare hard seekTo + reset speed 1f
- removed catch-up seekTo after +1s (was adding ~2s error)
- log now prints speed
AudioSyncPlayerTest: 18 cases (boundaries 150/2000, speed up/down/1f, play/pause).
