+- Added `MistralTTSService` for streaming text-to-speech using Mistral's Voxtral TTS API (`voxtral-mini-tts-2603`). Supports SSE-based audio streaming with automatic resampling from the API's native 24kHz to any requested sample rate. Requires the `mistral` optional extra (`pip install pipecat-ai[mistral]`).
