// Two interfaces:
// - `TranscriptionProvider` — speech → text
// - `TTSProvider` — text → audio

// Built-in concrete providers:
// - `EdgeTTSProvider` — uses the `node-edge-tts` package (no Python subprocess)
// - `CommandTTSProvider` — generic shell command with `{input}` / `{input_path}` / `{output_path}` placeholders
