## Task 1: Create Provider interface and registry - COMPLETE

Created internal/provider package with:
- Provider interface with all required methods
- ProviderConfig struct for API key storage
- 4 provider implementations: OpenAI, Groq, Mistral, ElevenLabs
- Registry with GetProvider(), ListProviders(), ListProvidersWithLLM(), ListProvidersWithTranscription()
- Comprehensive tests (all passing)

Key decisions:
- OpenAI and Groq support both transcription + LLM
- Mistral and ElevenLabs are transcription-only
- ValidateAPIKey checks prefix for OpenAI (sk-) and Groq (gsk_), accepts any non-empty for others
