/**
 * Voice Module - Unified Voice/Speech Integration for NeuroLink
 *
 * Provides TTS (Text-to-Speech), STT (Speech-to-Text), and
 * Realtime Voice capabilities across multiple providers.
 *
 * Use TTSProcessor (src/lib/utils/ttsProcessor.ts) for TTS.
 * Use STTProcessor (src/lib/utils/sttProcessor.ts) for STT.
 * Use RealtimeProcessor for realtime voice sessions.
 *
 * Importing this module also auto-registers every shipped TTS / STT /
 * Realtime handler whose backing API key is present in `process.env`.
 * Registration is idempotent and silently skipped on failure.
 *
 * @module voice
