data/voice/voice_service library
Voice mode service for the Flutter client.
Migrated from the Neomage TypeScript voice/ module. Provides:
- VoiceState enum (idle / recording / processing)
VoiceModetoggle state- Language normalization for speech-to-text
- Feature-flag and auth gating (simplified — no GrowthBook dependency)
