Consumers can now import from @framers/agentos/voice-pipeline:
  VoicePipelineError, AggregateVoiceError
  HealthyProvider, ProviderCapabilities, defaultCapabilities
  CircuitBreaker
  AudioRingBuffer
  TranscriptDedupe
  VoiceMetricsReporter
  StreamingSTTChain, StreamingTTSChain
  createVoiceProvidersFromEnv, NoVoiceProvidersAvailableError
