## 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

## Task 2: Refactor config to unified provider structure - COMPLETE

Added to internal/config/config.go:
- `Providers map[string]ProviderConfig` for centralized API key storage
- `Keywords []string` at config root level
- `LLMConfig` with Enabled, Provider, Model, PostProcessing, CustomPrompt
- `LLMPostProcessingConfig` with RemoveStutters, AddPunctuation, FixGrammar, RemoveFillerWords (all default true)
- `LLMCustomPromptConfig` with Enabled, Prompt
- `LLMAdapterConfig` struct for passing to LLM adapters
- `ToLLMConfig()` method
- `IsLLMEnabled()` helper
- `resolveAPIKeyForProvider()` - unified API key resolution: providers map -> legacy transcription.api_key -> env var
- `resolveAPIKeyForLLMProvider()` - same for LLM
- `migrateTranscriptionAPIKey()` - auto-migrates old config format
- `applyLLMDefaults()` - sets post-processing options to true if all are zero

Migration:
- Old configs with `transcription.api_key` auto-migrate to `providers` map on Load()
- Logs warning: "Run 'hyprvoice configure' to update config format"
- Both old and new config formats work (backward compatible)

Validation:
- LLM validation only runs when `llm.enabled = true`
- Checks provider is openai or groq
- Checks API key is available for LLM provider

Key decisions:
- API key resolution order: providers.X.api_key -> transcription.api_key -> ENV_VAR
- LLM provider names are "openai" and "groq" (not "groq-transcription")
- PostProcessing defaults to all true only if ALL options are false (zero values)
- Keywords at root level (global), used by both transcription and LLM
