VoiceState now carries a normalized mic amplitude (0..1) updated from the existing onAmplitudeChanged subscription, with a 0.02 change threshold so we don't spam rebuilds. VoiceMicButton swaps the constant-rate AnimationController for an AnimatedScale + animated glow driven by the live amplitude. 0.1 floor keeps the button breathing on silence; 120ms ease-out smooths between 200ms samples.
