Merge main's faster-whisper (local, free) with our Groq support into a unified three-provider STT pipeline: local > groq > openai. Provider priority ensures free options are tried first. Each provider has its own transcriber function with model auto-correction, env- overridable endpoints, and proper error handling. 74 tests cover the full provider matrix, fallback chains, model correction, config loading, validation edge cases, and dispatch.
