- TranscriptionProvider interface with transcribe() + isConfigured() - OpenAITranscriptionProvider: Whisper API (existing behavior) - AzureTranscriptionProvider: Azure Speech REST API for short audio - MockTranscriptionProvider: deterministic results for testing - Factory: getSTT() singleton with env-driven auto-detection - STT_PROVIDER=openai|azure|mock (explicit) - Auto-detect: AZURE_SPEECH_KEY → azure, OPENAI_API_KEY → openai, else mock - Config: add STT_PROVIDER, AZURE_SPEECH_KEY, AZURE_SPEECH_REGION env vars - Route refactored: audio download (common) → provider.transcribe() (swappable) - deriveFilename() extracted to types.ts (shared by route + providers) - 35 transcription tests (was 12), 171 total passing - Follows same pattern as @bytelyst/llm provider abstraction
