feat: Android VoIP client — Phase 2 (JNI bridge, Compose UI, AEC pipeline wiring)
- JNI bridge with 8 extern functions (init, startCall, stopCall, setMute, setSpeaker, getStats, forceProfile, destroy) with panic catching - Kotlin engine layer: WzpEngine JNI wrapper, WzpCallback interface, CallStats data class with JSON deserialization - Jetpack Compose UI: InCallScreen with quality indicator (green/yellow/red), mute/speaker/hangup buttons, stats overlay, duration timer - CallActivity with RECORD_AUDIO permission handling, Material3 theme - CallService foreground service with WakeLock, WiFi lock, notification - AudioRouteManager for speaker/earpiece/Bluetooth SCO switching - AEC wired into CallEncoder pipeline: AEC → AGC → denoise → silence → encode - AEC farend reference fed from decode path to encode path in pipeline - Engine exposes set_aec_enabled/set_agc_enabled via AtomicBool flags Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
